Hi! I am looking for a software to copy protect a powerpoint file on a USB stick, my customer has asked us for a solution to make it impossible (or hard atleast) to copy the file from USB. Does your software Copy Protect do this? I downloaded the free version to try it out but can’t test it without buying the program it seems like.
Two tools from Gilisoft—Gilisoft DRM Protection and Gilisoft Copy Protection—accurately meet your needs for protecting PowerPoint (PPT) files on USB drives. They not only support USB binding and anti-copying but also ensure smooth playback of animations, videos, and audio. Additionally, they address your concern about “being unable to test the full version.”
1. Precise Alignment Between Core Needs and Gilisoft’s Features
All your core requirements—storing PPTs on a USB, restricting use to that USB only, disabling copying/printing/sharing, ensuring smooth animations, and testing the full version—are fully covered by Gilisoft. Here’s the specific breakdown:
- USB Binding & Anti-Dissemination: Gilisoft Copy Protection lets you lock PPTs into non-sharable GCP format. Once the file is opened on a USB for the first time, it automatically binds to that device and cannot be opened on other computers or USB drives, completely preventing unauthorized copying and sharing.
- Comprehensive Permission Control: It supports disabling “copying, printing, and saving” functions. Even if someone gains access to the USB, they cannot extract file content or create copies. Meanwhile, unauthorized screen recording is blocked via strict encryption mechanisms.
- Smooth Playback Guarantee: Gilisoft’s encryption solution is optimized for PPT scenarios. It uses the AES encryption algorithm—same as that used by the NSA for “top-secret documents.” After encryption, PPT animations, embedded videos, and audio run smoothly without lag, distortion, or missing features.
- Suggestions for Testing the Full Version: Due to functional limitations of the free version (e.g., inability to add PPTX files), you can directly contact Gilisoft’s official customer service. Explain that you “need to test core functions like USB binding and animation smoothness,” and the official team usually provides temporary test access or a demo version to help you verify the 效果 before purchasing.
2. Comparing Competitors: Gilisoft’s Core Advantages
Most other PPT protection tools on the market have “functional shortcomings,” while Gilisoft balances both “security” and “playback experience.” The detailed comparison is as follows:
| Competitor Tool | Core Shortcomings | Gilisoft’s Improved Advantages |
|---|---|---|
| StarForce | Poor PPT animation display; insufficient adaptation to high-fidelity scenarios | Special optimization for PPT animation DRM; no loss of animation quality after encryption |
| Dingling Class | Low flexibility in device binding; difficulty in strictly binding to a specific USB | Supports precise USB device binding; files work only on authorized USB drives |
| Ordinary USB Anti-Copy Software | Focuses on device-level protection; PPT animations tend to lag or distort | Balances device binding and file-level DRM; maximizes smoothness of animations/audio/videos |
| Adobe Acrobat Pro DC | Can only convert PPTs to PDF for protection; cannot retain original PPT animations or USB binding | Encrypts original PPT formats directly; no file type changes; preserves all native functions |
3. Practical Recommendations for Using Gilisoft
- Step 1: Function Testing: Prioritize contacting Gilisoft official support (customer service access is available on the official website) to apply for “special test access for PPT USB protection.” Focus on verifying three scenarios: whether the PPT can be opened on other devices after USB binding, whether animations/videos run smoothly, and whether copying/screen recording functions are disabled.
- Step 2: Formal Encryption Operation: After successful testing, use Gilisoft Copy Protection to convert PPTs to GCP format. Select “Bind to Current USB” in the “Device Binding” option, and check “Disable Copying/Printing/Saving” at the same time. Once completed, save the encrypted files to the USB drive.
- Step 3: Post-Maintenance: If you need to replace the USB drive, you can use Gilisoft’s “Device Authorization Management” function to unbind the old USB and rebind a new one—no need to re-encrypt the files.
4. Reasons to Avoid Other Competitors (to Help You Avoid Pitfalls)
Most tools on the market have obvious shortcomings and are not recommended as first choices:
- Cross-platform encryption tools (e.g., Cryptomator, Boxcryptor): Only focus on file encryption, lacking PPT device binding and animation optimization functions, which cannot meet the demand for exclusive USB use.
- Cloud encryption tools (e.g., NordLocker, AxCrypt): Their advantages lie in cloud file transfer encryption, with no targeted design for “local USB PPT permission control” and “animation smoothness.”
- Platform-based tools (e.g., Dingling Class): Although they have good anti-screen recording effects, their device binding capability is weak, making it impossible to strictly restrict PPT use to a specific USB drive.
