Today, we received an inquiry from a user, and the content of his letter is as follows:

Hello. I used the free version of the program. But I can’t test it. I couldn’t add my Powerpoint (PPTX) files to the program. I want to test them? Does the pptx work smoothly after protection (encryption)? Animations work smoothly? How can I test the full version of the program? I want to buy the program after testing. Can you help me?

I want to do the following:

1. Upload my Powerpoint files to a USB
2. The owner of the USB should only use this file on the flash drive.
3. He can’t copy, print or save it.
4. He can’t share the contents of the flash drive with anyone else.
5. The animations, videos, and music in Powerpoint should work smoothly.

From the user’s letter, we can clearly sort out his core needs and possible usage scenarios, which are also common problems encountered by many users who have the need to protect PPT files, such as how to realize PowerPoint USB encryption, PPT anti-copy and anti-print, and protect the smooth playback of PPT animations.

First, looking at the core needs, the user wants to store PowerPoint files on a USB, and the file can only be used on that USB. It is not allowed to be copied, printed, saved, or shared with others. At the same time, it is necessary to ensure that the animations, videos, and music in the file can run smoothly. In addition, because the free version cannot add PPTX files for testing, the user wants to know how to test the full version and plans to buy it after testing, which also reflects his emphasis on the practicality and adaptability of the software.

Then, analyzing the possible usage scenarios, such needs are likely to appear in business cooperation, academic exchanges, or internal data sharing. For example, a company’s salesperson needs to carry a PPT containing the core product plan to visit customers. In order to prevent the plan from being obtained by competitors, it is necessary to restrict the file to be used only on a specific USB and not to be copied and spread. When researchers share PPTs of their research results at academic conferences, they will also have similar restrictive needs to protect the confidentiality and originality of their research. In these scenarios, the security of the file is the primary consideration, and at the same time, it must not affect the normal display effect of the PPT, otherwise, it will affect the quality of communication.

In the field of PowerPoint file protection, there are many competitors in the market, and different products have their own characteristics in PPT encryption, anti-screen recording, and animation retention.

StarForce PPT Copy Protection can convert PPT or PPTX files into applications for protection, prevent files from being copied, edited and modified, block screen capture, and control file distribution. The protected presentation runs in demo mode and supports binding files to CD, DVD, USB storage devices, etc. However, there may be room for optimization in the perfect presentation of animation effects, which may not be ideal for users who need high-fidelity display of PPT animations.

Dingling Class, as a PPT encryption distribution authorization and sharing platform, performs well in anti-screen recording. As long as you enable courseware encryption with one click, the corresponding content can only be played in its client. No matter in local or remote sharing, or screen projection, it is impossible to take screenshots and record screens, which fully protects intellectual property rights. Moreover, it can perfectly reproduce the animation effects and audio-visual effects of complex PPTs. However, in terms of the flexibility of restricting the use of devices for files, compared with some software specially designed for device binding, it may be slightly insufficient, and it is difficult to meet the needs of strictly binding PPT to a specific USB.

There are also some specific USB anti-copy and anti-copy software, which have the functions of file anti-copy, anti-screenshot, and anti-screen recording, and can prevent virus damage. Put courseware PPT and other files on a protected USB flash drive or mobile hard disk, and others can open and view them but cannot copy them. However, such software often focuses more on the protection at the storage device level. For the DRM (Digital Rights Management) function of the PPT file itself, in terms of retaining details such as animations, it may not be precise enough, and animation freezes or distortions are prone to occur.

Adobe Acrobat Pro DC also has certain file protection capabilities. It can merge PPT and other different format files into PDF, and set “document protection” to prevent others from copying, printing, and editing the information. But it mainly focuses on PDF files, and is not specialized in device restrictions and animation DRM for original PPT files, so it cannot well meet the user’s needs for using PPT on USB and retaining animations.

Boxcryptor, as an outstanding document encryption tool, adopts high-intensity encryption algorithms such as AES-256 and RSA. Its encryption ability is excellent, but it lacks targeted optimization in PPT file playback scenarios, such as anti-screen recording and ensuring animation fluency, so it has limited practicality for users focusing on PPT protection.

Cryptomator is a cross-platform open-source software that uses client encryption technology and AES-256 encryption algorithm to encrypt and obfuscate file names and folder structures, and provides a virtual drive interface to make encryption operations transparent. However, it has no outstanding performance in the specific protection of PPT files, such as restricting the use of devices, preventing screen recording, and ensuring DRM for PPT animations, so it is difficult to meet the personalized needs of users.

AxCrypt is easy to operate. You can encrypt files with a right click, and it can also automatically encrypt and upload to the network disk to achieve cross-device synchronization. However, it has no special functional design in protecting PPT files for use on specific devices, preventing unauthorized screen recording, and maintaining the integrity of PPT animations, so it cannot cope with complex PPT protection scenarios.

NordLocker provides end-to-end encryption. After files are encrypted, they are transmitted to the cloud, and only users know the key. However, its advantages are more reflected in cloud file transmission encryption. It does not provide effective solutions for restricting the use of PPT files on local devices, preventing screen recording, and ensuring the normal operation of animations, so it is not suitable for scenarios where PPT needs to be used on USB.

If you want to find a more comprehensive solution to meet the above needs, Gilisoft will be an excellent choice. Gilisoft DRM Protection can securely encrypt PowerPoint files. It uses the Advanced Encryption Standard (AES), the same encryption algorithm used by the National Security Agency (NSA) for “top-secret” documents, which can provide government-level security and is a reliable PPT encryption tool.

With Gilisoft Copy Protection, you can lock PPT files to authorized devices, which can ensure that files will not be shared by others, and at the same time prevent illegal copying and distribution, perfectly realizing the function of PPT anti-copy and anti-print. You can create non-sharable GCP files. When the end user opens the protected PPT for the first time, he will be prompted that the file has been registered to his device and cannot be opened on other devices, meeting the need to bind PPT to USB. In terms of anti-screen recording, Gilisoft effectively prevents unauthorized screen recording through a strict encryption mechanism. Moreover, Gilisoft ‘s encryption method is specially designed to ensure that the original functions of the file such as animations, videos, and music are not affected. The encrypted files will not have any freezes or quality loss during playback or demonstration, and perform excellently in the DRM function of retaining PPT animations, allowing PPT animations to play smoothly.

If you want to test the full version of our program, you can visit our official website and follow the prompts to try it out. We believe that after testing, you will find that Gilisoft ‘s solution fully meets your needs. Whether it is PowerPoint USB encryption, anti-copy, or retaining animation effects, it can be done excellently, and then you can make a wise purchase decision.

“I encrypted my video with Gilisoft DRM Video Protection. A user can’t watch it after replacing their hard drive, getting a message saying ‘Illegal password, inconsistent with the current machine code!’ How can I help them reactivate it?” This is a question from a video creator consulting technical support. In today’s era of increasingly convenient digital content dissemination, video creators want to protect their intellectual property and prevent unauthorized copying and distribution of their works, while also hoping to properly handle various issues users encounter during use. Gilisoft DRM Video Protection perfectly meets both needs, acting like an intelligent protection and authorization system for video content, allowing creators to avoid the difficult choice between copyright protection and user experience.​

In fact, the situation the user encountered is exactly how Gilisoft DRM Video Protection’s hardware-binding mechanism works. This mechanism effectively prevents videos from being illegally copied and played on other devices, curbing piracy at the source. At the same time, it fully considers the reasonable need for users to replace hardware devices, designing a complete secondary authorization solution that allows creators to easily help users solve problems.​

An instructor from a vocational skills training platform had a similar experience. He carefully produced a set of paid courses, encrypted them with Gilisoft DRM Video Protection, and launched them on the market. Soon after, a student reported that they couldn’t watch the course videos after replacing the hard drive of their computer due to damage. Following the software’s operation guidelines, the instructor quickly resolved the issue for the student. He first asked the student to find the new machine code on the player end and send it over. Then, he opened the Gilisoft DRM Video Protection software, entered the “Generate Playback Password” module, selected the corresponding course project, entered the original encryption key, pasted the new machine code provided by the student, and clicked the generate button. A new playback password was then created. After entering the new password, the student successfully resumed access to the course and even sent a message to the instructor praising: “I didn’t expect the problem to be solved so quickly after replacing the hard drive. It didn’t affect my study at all. Great job!”​

The specific steps to regenerate the playback password using Gilisoft DRM Video Protection based on the new machine code are as follows (based on the software’s general operation logic; there may be slight differences between versions):​

1. Obtain the user’s new machine code: Ask the user to open the video playback interface or DRM authorization window on the computer with the video player installed, find and record the new “machine code” (usually a combination of letters and numbers, which the user can directly copy or send via screenshot).​

2. Open the Gilisoft DRM Video Protection software: On your computer used for encrypting videos, launch the Gilisoft DRM Video Protection main program and enter the software’s main interface.​

3. Access the password generation function module: Find and click the function button related to “Generate Playback Password”, which may usually be displayed as “Create Playback Password”, “Generate Authorization Password” or similar names (this function is generally located in the software’s “Authorization Management”, “Password Generation” or the settings of the corresponding video project).​

4. Enter key information: In the pop-up password generation window, fill in the following information: select the corresponding video project (or enter the “Project ID” used during original encryption); enter the “Original Encryption Key” (Encryption Key) used when encrypting the video; paste the “new machine code” provided by the user; (optional) set permission parameters such as password validity period and playback count (if supported by the software).​

5. Generate the new password: After confirming that the information is correct, click the “Generate”, “Create” or “OK” button. The software will calculate and generate a new playback password based on the new machine code.​

6. Send the new password to the user: Send the generated new password (usually a string of characters) to the user, and ask them to enter the password on the player end to complete the authorization verification and play the video.​

This standardized operation process not only builds a solid defense line for copyright protection through the hardware-binding mechanism, preventing creators’ efforts from being easily stolen, but also properly addresses users’ reasonable demands through flexible secondary authorization, avoiding user loss due to technical issues.​

With its features of “strict protection, easy operation, and flexible authorization”, Gilisoft DRM Video Protection has become a powerful assistant for many video creators. By choosing it, creators can not only focus on creation without worrying about piracy, but also quickly provide solutions when users encounter device changes, enhancing users’ recognition and trust in their works, and achieving a two-way improvement in copyright protection and user experience.​

In this era of information explosion, sound is no longer just a simple communication tool, but a core carrier of creativity, emotions, and personality. Whether it’s the interesting dubbing in short videos, the unique voice in podcasts, or the vivid explanations in teaching scenarios, high-quality voice content can always capture the audience’s attention instantly. Now, the upcoming VoiceLabPro, as an all-in-one voice processing software, is opening a new world for everyone who pursues excellence in sound.

AI-Powered Sound: Features That Surpass Imagination

The core charm of VoiceLabPro lies in its deep integration of cutting-edge AI technology with practical functions, making complex voice processing accessible to all.

If you’re an audio creation enthusiast, the File Voice Change feature will impress you: import an ordinary recording, and whether you want to transform it into the iconic voice of a classic movie character or an interesting regional accent, a wealth of preset voice templates can achieve it with one click. You can also manually adjust pitch, speed, and timbre to make every piece of sound full of personality—dubbing for animation characters, adding special effects to game clips, and creativity knows no bounds.

Music lovers will be captivated by the AI Cover feature: it doesn’t alter any details of the original song, yet allows you to “sing” your favorite songs with your own voice. Simply upload the original song and a sample of your voice, and AI will act like a “lossless replacement” to replicate the entire song with your timbre. The original melody’s ups and downs, rhythm, and even the singer’s breathing and emotional tension are all preserved intact. The only difference is that the “singer” becomes you. Even if you’re not a perfect singer, you can have a flawless “self-sung” version, giving your favorite songs a unique voice imprint that belongs exclusively to you.

The Voice Cloning feature is nothing short of “black technology”: with just a clear audio sample, VoiceLabPro can accurately extract sound features and generate a highly similar exclusive voice. Use your own voice to create audiobooks, have your idol’s voice read copy, or even build a unique “sound IP” for a brand. Privacy protection and data encryption technologies ensure worry-free creation.

More Than “Fun”: A Double Guarantee of Efficiency and Quality

The power of VoiceLabPro goes beyond creative gameplay—it truly solves pain points in creation.

Worried about background noise ruining the quality of your podcast? The Intelligent Noise Reduction feature comes to the rescue: whether it’s wind noise from outdoor interviews, current noise from old recordings, or ambient chatter, AI can accurately identify and remove them while preserving the natural texture of the human voice, making the audio instantly clear and clean.

Want to extract pure vocals from a live recording? Vocal-Background Separation makes it easy: AI algorithms act like a “scalpel” to separate pure vocal tracks from background sounds. Vocals can be used for post-dubbing, and background sounds can be reused as sound effect materials, eliminating the hassle of processing complex audio.

For scenarios requiring large amounts of voice content, the Text-to-Speech feature is an “efficiency tool”: input text, and you can choose a suitable timbre from the system’s preset high-quality voice library or directly use your cloned voice to generate natural and smooth speech. It even supports adjusting emotional tones—joy, sadness, seriousness… making text “speak” with inherent appeal. If you can’t find a satisfactory timbre, you can contact the official team to customize an exclusive voice, truly achieving “voice freedom.”

In the context of the increasing popularity of mobile office, the USB tethering function of mobile phones brings great convenience to us. However, at the same time, it also brings many potential risks to the data security of computers. It is crucial to understand these risks and take effective measures to disable this function to ensure data security.​

I. Functions of USB Tethering​

Simply put, USB tethering is a function that shares the mobile phone’s network connection with other devices such as computers through a USB data cable. When we are in an environment without Wi-Fi or wired network, we only need a USB cable to connect the mobile phone and the computer, and turn on the USB tethering function of the mobile phone. Then the computer can access the Internet through the mobile phone’s mobile data (4G, 5G) or the connected Wi-Fi network. Compared with Wi-Fi hotspot sharing, this method has a more stable connection, less interference, and a relatively higher data transmission rate. Moreover, while sharing the network, data can be transmitted between the mobile phone and the computer through the data cable, which can be said to kill two birds with one stone. For example, when it is necessary to handle urgent work tasks outdoors and there is no available network around, USB tethering can come in handy, allowing the computer to quickly connect to the network and carry out work.​

II. Risks to Computer Data Security​

(I) Network Boundary Breakthrough​

For confidential computers or computers in internal private networks, they should maintain strict physical isolation from the Internet. However, once connected via mobile phone USB tethering, it is like opening a gap in the originally closed network boundary, allowing the computer to directly access the public network. This undoubtedly provides an opportunity for external malicious attackers, who can easily bypass the originally complex network protection system, directly enter the internal network, and steal or tamper with data in the computer.​

(2) Malware Propagation​

As a device connected to the public network, mobile phones are faced with many threats from malware in daily use. When a mobile phone is connected to a computer via USB and shares the network, the hidden malware on the mobile phone is very likely to infect the computer through this opportunity. Once these malware run on the computer, they may perform various dangerous operations, such as stealing users’ login accounts, passwords and other sensitive information, transmitting important files in the computer to external servers, and even controlling the computer’s hardware devices, causing serious damage to the computer system. Moreover, since computers are often in an office network environment, malware may further spread to the entire office network using the computer as a springboard, leading to larger – scale data security accidents.​

(3) Risk of Data Leakage​

Malicious users can use the connection of mobile phone USB tethering to actively transmit confidential files, trade secrets and other important data in the computer to the outside through the mobile phone network without the computer user’s knowledge. In addition, some malware may automatically scan files in the computer in the background, screen out sensitive data and quietly send them out through the mobile phone network. Because data transmission is carried out through the mobile phone as an intermediate device, it becomes more difficult to track the source of data leakage, which greatly increases the risk and loss of data leakage.​

III. Methods and Disadvantages of Disabling USB Tethering​

(I) BIOS/UEFI Settings​

When the computer starts, press a specific key (the key may vary for different brand computers, commonly F2, F10, Delete, etc.) to enter the BIOS/UEFI settings interface. In the BIOS/UEFI menu, find the settings related to USB, which are usually located under the “Advanced” or “Security” menu. Here, set “USB Controller”, “USB Support” or similar options to “Disabled”. Save the settings and exit BIOS/UEFI. After the computer restarts, all USB ports will be disabled, including the ports used to connect mobile phones to implement USB tethering.​

This method has significant disadvantages. It disables all USB ports, which means that common USB devices such as USB mice, keyboards, and U disks cannot be used normally, seriously affecting daily work and operations. Users need to prepare additional non – USB interface devices for replacement, bringing great inconvenience.​

(2) Device Manager Disabling​

Right – click the “Start” button and select “Device Manager”; or enter “Device Manager” in the search bar and open it. In Device Manager, find “USB Controllers” or “Universal Serial Bus Controllers”. After expanding this option, right – click the USB Root Hub you want to disable and select “Disable Device”. After performing this operation, all USB devices connected to this controller will be unavailable, including the mobile phone connection used for USB tethering.​

The disadvantage of this method is that it can only disable the controller corresponding to the currently connected USB device. If you replace the USB port to insert a new device or re – enable the disabled controller, the device can still be recognized and used. It cannot fundamentally and long – term prevent the activation of the USB tethering function, and the protection effect is limited and unstable.​

(3) Group Policy Settings​

For Windows systems, run “gpedit.msc” to open the Group Policy Editor. In the Group Policy Editor, expand “Computer Configuration” → “Administrative Templates” → “System” → “Device Installation” → “Device Installation Restrictions” in sequence. Find the option “Prevent installation of devices not described by other policy settings” or “Prevent installation of removable devices”, double – click to open it, select “Enabled”, and then click “OK”. In this way, you can prevent the computer from installing new USB devices, thereby preventing mobile phones from connecting to the computer through the USB tethering function.​

However, this method only takes effect on devices that comply with group policy rules. For some devices that have undergone special driver modifications or can bypass group policy detection, it may not be able to completely prevent their connection, resulting in certain security vulnerabilities. Moreover, the steps of group policy settings are relatively complex. For non – professional users, the operation is difficult, and it is easy to set errors, leading to abnormalities in other functions.​

IV. GiliSoft USB Lock Helps Solve the Problem​

From the disadvantages of the above three methods, it can be seen that when disabling USB tethering, they either affect the normal use of other devices, or have poor protection effects, or are complicated to operate. As a professional third – party software, GiliSoft USB Lock shows significant advantages of being convenient, simple and having no side effects in disabling USB tethering.​

[San Francisco, March 15, 2025] – As online video content becomes the lifeblood of industries ranging from education to digital marketing, creators and rights holders face a dual challenge: protecting their work from unauthorized access while making their brand stand out in a crowded digital landscape. Today, Free Video DRM, a leading free video DRM protection solution, announces three groundbreaking features—Password Blacklist, Customizable Player, and Web Page Integration—designed to address these critical needs. This update marks a shift from basic content protection to an all-in-one tool that integrates security, branding, and user engagement.

Tackling Piracy at Its Source: Password Blacklist Blocks Leaks Proactively

Password sharing and credential leaks remain top threats to video monetization. A 2024 survey by the Digital Content Protection Association found that 58% of premium video creators lose revenue due to unauthorized password sharing, with weak or compromised passwords accounting for 70% of security breaches.

The new Password Blacklist feature revolutionizes traditional protection methods. Instead of relying solely on static password requirements, creators can now proactively block access from known leaked passwords, shared credentials, or weak passwords (e.g., “123456” or “password”). This dynamic defense cuts off unauthorized access at the entry point, boosting protection efficiency by 40% compared to traditional password systems in beta tests with educational content creators.

“Just setting a password is no longer enough—bad actors exploit shared or leaked credentials to bypass protections,” says Emily Chen, Product Lead at Free Video DRM. “Our Password Blacklist gives creators the power to defend proactively: if a password circulates on the dark web or forums, they can block it instantly, turning reactive damage control into proactive defense.”

Custom Player & Branded Icons: Turn Videos into Brand Ambassadors

Standing out among generic players is key to boosting audience retention. Free Video DRM’s Customizable Player feature lets creators design interfaces that align with their brand identity—incorporating logos, visual elements, and color schemes to eliminate the “generic feel” of third-party players.

For example, a fitness instructor launching a paid course can embed their logo into the player, use brand colors for playback controls, and add a custom “subscribe” button, turning every view into a brand touchpoint. Early users report a 25% increase in brand recall after switching to custom players, far outperforming default tools.

“Videos aren’t just content—they’re an extension of your brand,” emphasizes Emily Chen. “Why let a generic player dilute your identity? Our tool lets creators infuse every frame and interaction with their unique brand essence.”

Web Page Integration: Closing the Loop on Viewer Engagement

Beyond security and branding, Free Video DRM’s new Web Page Integration feature helps creators turn passive viewers into active participants. It allows embedding related web content—such as course syllabi, product specs, or feedback forms—directly within the video player, creating a seamless “watch-learn-act” journey.

A corporate trainer, for instance, can link a training video to a quiz page to ensure employees apply what they’ve learned. A YouTuber launching merchandise can embed a shopping link to drive immediate conversions. Beta data shows a 30% jump in post-video engagement (clicks, form submissions, purchases) after adding integrated web content.

Industry Impact: Redefining the Standard for Free DRM Tools

Unlike many free DRM solutions that focus solely on encryption, Free Video DRM combines security, branding, and engagement—filling a gap for small businesses, educators, and independent creators who lack enterprise budgets but need professional-grade tools.

“Creators shouldn’t have to choose between protecting their work and growing their brand,” says Emily Chen. “These features are our answer: a free tool that doesn’t just lock down content, but helps it thrive.”

Here is a summary of the core differences between Gilisoft USB Encryption (a dedicated USB drive encryption tool) and Gilisoft   File Lock Pro (a comprehensive file security tool) in terms of user groups, features, and application scenarios:

I. Differences in User Groups

Typical Users of USB Encryption

• Enterprise IT Departments / Data Security Managers: Need centralized control over USB drives, such as separating confidential and public areas (e.g., technical documents vs. public materials in internal corporate collaboration), and can accept administrator permission requirements.
• Research Institutions / Military-Industrial Units: Have extremely high demands for USB encryption strength, requiring resistance to brute-force attacks and physical tampering, such as using AES-256 algorithms for underlying partition modification.
• Fixed Partners / Supply Chain Stakeholders: Transfer data between controlled devices (e.g., design institutes exchanging drawings with construction parties) where both sides can coordinate to provide administrator permissions.

Typical Users of Gilisoft File Lock Pro

• Individual Users / Freelancers: Need to protect both local private files (e.g., photos, diaries) and work materials on USB drives, and prefer a single tool to cover all scenarios.
• Business Professionals Frequent Sending Files: Need to generate standalone encrypted EXE files (decryptable without software installation), such as lawyers sending contracts or designers delivering work.
• Users of Public Devices: Often need to access USB drives in environments without administrator permissions, such as internet cafes or school computer labs—for example, students submitting assignments or job seekers presenting resumes.

II. Core Differences in Features

Core Features of USB Encryption

• Full USB Encryption & Partition Isolation: Divides the USB drive into a “secure zone” (password-required access) and a “public zone” (direct read/write). For instance, enterprises can store technical solutions in the secure zone and meeting minutes in the public zone.
• High-Strength Underlying Encryption: Achieves physical-level protection by modifying the USB drive’s partition table. Encrypted files cannot be recovered by ordinary tools, making it suitable for storing core data.
• Limitations in Cross-Device Compatibility: Requires administrator permissions to install drivers when first used on another person’s computer, and encryption speed may be slow (e.g., 50% performance drop during large file transfers).

Core Features of Gilisoft File Lock Pro

• Multi-Scenario File Protection:
  • Local File Encryption: Supports hiding files/folders (invisible even in safe mode) and setting read-only permissions (preventing modification or deletion).
  • Flexible USB Encryption: Allows encrypting only specific folders, with encrypted files retaining their original formats (e.g., Word, Excel) for normal editing.
  • Additional Security Tools: File shredding (permanently destroying sensitive files), log auditing (recording access operations), and time-locking (restricting file usage duration).
• No Dependence on Administrator Permissions: On others’ computers, simply run the decryption program and enter the password to access—for example, no technical support is needed when demonstrating encrypted solutions on a client’s computer.
• Cross-Platform Compatibility: Supports Windows and macOS, with generated EXE files decryptable on any system, ideal for international collaboration.

III. Scenario Differences & Selection Recommendations

Scenarios Where USB Encryption is Preferred

1. Enterprise-Level Partition Management Needs:
   • Example: A manufacturing enterprise requires technical department USB drives to have encrypted zones (storing product design drawings) and public zones (storing production process instructions), limited to internal computer use.
   • Note: Accept slower encryption speeds (e.g., transferring 10GB files may take 50% longer) and potential file corruption risks.
2. Environments with High Physical Security Threats:
   • Example: Research teams storing genetic data on USB drives in laboratories need protection against physical disassembly and cold-boot attacks (i.e., stealing keys via memory).
3. High-Strength Transfers Between Fixed Devices:
   • Example: Design institutes and construction parties exchanging drawings via USB drives, where both IT departments can coordinate administrator permissions but require encrypted files to be unbreakable by third-party tools.

Scenarios Where Gilisoft File Lock Pro is Preferred

1. Public Environments Without Administrator Permissions:
   • Example: Students submitting encrypted assignments in school labs or job seekers showcasing encrypted portfolios at recruitment events—access is granted directly with a password, no system permissions required.
2. Mixed-Scenario Protection Needs:
   • Example: Freelancers need to encrypt both local financial reports (preventing prying eyes) and client data on USB drives, managed via a single tool.
3. Flexible File Sharing & Collaboration:
   • Example: Lawyers generating encrypted EXE files for clients, who can double-click to decrypt and view contracts without installing software.
   • Designers can hide source files (e.g., PSD formats) on USB drives and only display JPG previews to prevent unauthorized copying.

IV. Key Risks & Trade-Offs

• Potential Risks of USB Encryption:
  • Performance Loss: Encryption may slow down USB read/write speeds, and frequent operations may cause file corruption.
  • Poor Cross-Device Compatibility: Inaccessible on computers without driver installation—e.g., re-authorization is needed if partners temporarily switch devices.
• Potential Risks of Gilisoft File Lock Pro:
  • Limited Encryption Depth: Relies on software-layer password verification; if the USB drive is physically lost, it may be bypassed by professional tools (e.g., key extraction via memory).
  • Scattered Features: Local file management functions may seem redundant if only USB encryption is needed.

Summary: How to Choose?

• Choose USB Encryption if you need physical-level USB encryption and partition isolation, and can accept administrator permission requirements and performance losses—e.g., for internal enterprise sensitive data transfers.
• Choose Gilisoft File Lock Pro if you need permission-independent flexible encryption and multi-scenario coverage—e.g., personal privacy protection, frequent file sharing, or use on public devices.

The essential difference lies in this: USB Encryption is a “physical defense” tool, while Gilisoft File Lock Pro is a “permission-based protection” tool. The choice depends on balancing security, convenience, and costs in practical scenarios.
