What Would You Like to Do?

Lock or Unlock Local Files and Folders

Use Locking File to manage access on the protected Windows PC. The unlock control belongs to the same managed list; use File Encryption when you need a separate protected output.

Open the local Locking File workspace

Open GiliSoft File Lock Pro with the management password, then choose Local Disk > Locking File. Start with a noncritical sample so you can check both locking and unlocking.

Local Disk > Locking File has Lock Files/Folders, Lock Drive, Unlock, Set to lock, Status, and Refresh.

Add the file or folder to lock

Select Lock Files/Folders and choose the intended item. Review its path in the File / Folder / Drive List. Lock Drive is a separate choice for a supported local data drive, not a requirement for locking one folder.

Apply the lock and check access

Select the listed item and use Set to lock when needed. Review Status and Refresh, then test opening the item through Windows Explorer. Locking controls local access; it does not create an encrypted transfer file.

Unlock the item and verify normal access

Return to Local Disk > Locking File, select the managed item, and choose Unlock. Refresh the list and confirm the file or folder opens normally. Keep the management password and recovery information available.

Protect
Keeps content readable while restricting modification, deletion, renaming, moving, or writing.
File Encryption
Creates a separate GFL or EXE output with its own opening and decryption workflow.

Hide Files, Prevent Changes, or Monitor a Folder

Hide or Unhide Files, Folders, and Drives

  1. Choose Hiding File and add the target

    Open Local Disk > Hiding File. Use Hide Files/Folders for selected content or Hide Drive for a supported local data drive.

  2. Review and apply the hidden state

    Select the listed item, use Set to hide when needed, and review Status. Check ordinary Windows browsing using a sample item first.

  3. Use Unhide to restore visibility

    Return to Hiding File, select the managed item, and choose Unhide. Use Refresh and confirm the original item is visible and opens normally.

Hiding File provides separate controls for files/folders and a local drive, plus Unhide and Set to hide.

Prevent Editing, Renaming, or Deletion

  1. Add the target in Protecting File

    Open Local Disk > Protecting File. Select Protect Files/Folders or Protect Drive for the intended item.

  2. Apply protection and test a sample

    Select the listed item and use Set to protect. Review Status and test reading, editing, renaming, moving, and deletion using noncritical data. This is local change protection, not encrypted output.

  3. Use Unprotect before making changes

    Select the item in the same workspace and choose Unprotect when changes should be permitted. Refresh and confirm normal editing or deletion is available again.

Protecting File has Protect Files/Folders, Protect Drive, Set to protect, and Unprotect controls.

Monitor Changes in a Folder

  1. Add the directory to monitor

    Open Local Disk > Folder Monitor, select Add, and choose the intended directory. Use Advanced Settings for the options offered by the installed app.

  2. Make a sample change and refresh the records

    Perform a noncritical test action in that directory, return to Folder Monitor, and select Refresh. Inspect the lower Time and Event log.

  3. Export records or stop monitoring the directory

    Use Export for a copy of the event records. Keep the export before clearing a log; use Remove for a selected monitored directory when it should no longer be listed.

The upper list contains monitored directories; the lower Time and Event panel has separate Refresh, Export, and Clear controls.

Protect External Storage or a Network Shared Folder

Use External Disk for removable storage and Shared Folder for a LAN share. These are separate workspaces with different target lists.

Lock Files on a USB or External Drive

  1. Connect and identify the intended drive

    Connect the USB or external drive and confirm the drive letter and folder path in Windows. Keep the management password available.

  2. Add and lock the selected content

    Open External Disk > Locking File, use Lock Files/Folders, and add the intended files or folders. Select the item and apply Set to lock when needed.

  3. Verify access and use Unlock when finished

    Check the status and test the selected content. Return to this managed list and use Unlock to restore access. If the goal is a protected file for transfer, use File Encryption instead of assuming a local rule is portable.

External Disk > Locking File manages selected files and folders on removable storage.

Hide Files on a USB or External Drive

  1. Connect the removable storage

    Connect the intended USB or external drive before choosing its files. Confirm the drive letter and path.

  2. Use the external Hiding File list

    Open External Disk > Hiding File, choose Hide Files/Folders, and add the intended content. Select it and use Set to hide when needed.

  3. Check visibility and restore it with Unhide

    Review the status and ordinary browsing. Return to the external Hiding File list and choose Unhide when the files should be visible again.

The external Hiding File screenshot is an empty target list; connect the drive before choosing content.

Lock or Unlock a Network Shared Folder

  1. Make the intended share reachable

    Connect to the correct LAN and confirm the shared folder is reachable with the required Windows permissions.

  2. Choose the shared-folder locking route

    Open Shared Folder > Locking File. Use Lock Folder, select the intended share, and apply Set to lock to the listed folder when needed.

  3. Test access and restore it with Unlock

    Check the result from the intended client computers and accounts. Select the share in the managed list and use Unlock when access should be restored; do not infer network-wide behavior from only one local test.

Shared Folder > Locking File has Lock Folder, Set to lock, Unlock, and a separate Folder List.

Create and Open Encrypted Files

Create Encrypted GFL or EXE Output

  1. Add the source files or folders

    Open More Tools > File Encryption and select Add Files/Folders. Review the source list and keep an independent backup.

  2. Choose GFL or EXE and set the password

    Select Encrypt to gfl or Encrypt to exe. Complete the password and destination choices offered by the software. GFL is opened with File Lock Pro installed; EXE provides an executable opening route.

  3. Create and test the protected output

    Wait for creation to finish, identify the output file, and test its opening password and decryption. Keep the original source until the result has been checked.

File Encryption offers Encrypt to gfl and Encrypt to exe. Its on-screen instructions also describe how each output is opened.

Open and Decrypt a GFL or EXE File

  1. Identify the encrypted output type

    Use the completed .gfl or .exe output, not the original source files. Keep the encryption password and sufficient destination space available.

  2. Open it through the matching route

    For GFL, install GiliSoft File Lock Pro on the Windows computer and open the GFL file. For EXE, run the generated executable. Enter the required password and choose the archive or extraction directory offered by the opening workflow.

  3. Check the extracted files

    Wait for completion, open the extracted documents or media, and check their contents. Decryption produces accessible files in the chosen destination; manage those copies separately from the encrypted output.

The File Encryption screenshot states the installed-app requirement for GFL and the executable route for EXE.

Shred Selected Files and Folders

File Shredder is for disposable data, not temporary hiding or locking. Keep required backups before adding a target.

  1. Add only the disposable files or folders

    Open More Tools > File Shredder and use Add Files/Folders. Review the selected paths and use Remove or Clear to correct the list.

  2. Review the operation before Safe Delete

    Inspect Advanced Setting as needed and confirm the intended targets. Add drive and Disk Wiper are separate drive operations; do not use them when you only mean to delete one file.

  3. Confirm the intended deletion and wait

    Use Safe Delete for the selected files or folders and wait for completion. Check the target result; Unlock and Unhide are not recovery controls for shredded content.

File Shredder shows Add Files/Folders, Add drive, Disk Wiper, Safe Delete, and Advanced Setting as separate controls.

Do not assume overwriting is a complete sanitization method for every SSD or flash device, or that deleting one copy removes backups and synced copies. Read the Windows file-shredding guide for deletion-scope considerations.

Manage Passwords, Reopening, and Program Records

Change the Management Password

  1. Open Change Password

    Choose Settings > Change Password. The pictured trial restricts password changes until registration; use the controls available in the installed version.

  2. Set and confirm the password

    Enter the same new management password in New Password and Confirm Password, then select the password section Change button when available. Store it securely.

  3. Verify management access

    Confirm that you can reopen File Lock Pro and manage a sample protected item. Set the recovery email before relying on hidden or locked content; the management password is separate from an encryption-output password.

Change Password has separate password and email sections with their own Change buttons. The screenshot includes a trial limitation notice.

Set the Recovery Email

  1. Find the separate email section

    In Settings > Change Password, locate Change Email below the password fields. The settings screenshot shows both areas.

  2. Enter and confirm an accessible address

    Complete New email and Confirm email, then use the email section Change button. Review Notify to email when relevant to the notification setup.

  3. Keep the access information available

    Review the configured address before changing the management password or hiding entry points. For lost access, use the recovery/help route in the installed app or GiliSoft support; a recovery email does not restore shredded files.

Configure Wrong-Password Responses

  1. Open Self Protect

    Choose Settings > Self Protect and locate Security, above the separate stealth controls.

  2. Review the email and lockout options

    Choose the intended alarm-email or temporary-login-ban option. The screenshot describes more than five incorrect attempts and a ten-minute temporary ban; check the installed wording rather than assuming editable thresholds.

  3. Check the notification and recovery setup

    Review the configured email address for alerts and retain a known management password and recovery route.

Self Protect separates repeated-password responses from desktop, Start menu, quick-link, and shell-menu visibility.

Configure Stealth and Shortcut Options

  1. Keep a working launch method

    Confirm the management password, recovery email, and a known way to reopen File Lock Pro before hiding any entry points.

  2. Select the intended visibility options

    Open Settings > Self Protect and review the Invisible (Stealth) Mode options for the desktop, Start menu, quick link, and shell menu. The Self Protect screenshot shows these controls.

  3. Verify reopening and reverse unwanted options

    Check that the chosen entry points behave as intended and the retained method still opens the app. Return to Self Protect and clear the relevant option when an entry point should return.

Set Automatic Locking for Restart or Hibernation

  1. Open General settings

    Choose Settings > General settings and review the option to automatically lock listed files or folders when the system hibernates or restarts.

  2. Review and enable the intended list

    Select the automatic-locking option and use Add Files/Folders for the intended items. Review paths; use Remove or Clear to correct the list.

  3. Test the configured event and unlocking

    Save your work and test the intended restart or hibernation event with noncritical data. Confirm the selected content is locked afterward and that you can restore access from Locking File.

General settings shows an automatic-locking checkbox and a separate Files/Folders list; it is not a clock-time scheduler.

View or Export the Program Log

  1. Open the program event list

    Choose Settings > Program Log and review Enable Log Function. This list is distinct from monitored-directory events.

  2. Refresh and inspect the records

    Select Refresh and review the Time and Event columns for the available records. Use Folder Monitor for directory activity instead.

  3. Export before clearing the list

    Use Export when you need a retained copy. Check that export before choosing Clear. Review the Exclude List separately when managing protection scope.

Program Log has Enable Log Function, Time and Event columns, Refresh, Export, and Clear.

Fix Common File Protection Problems

A hidden item is missing

Open the matching local or external Hiding File list, select the item, and use Unhide. Confirm the original drive is connected.

A file is readable but cannot be changed

Check Protecting File and use Unprotect for the managed item when editing should be allowed again.

An external target is unavailable

Reconnect the intended drive and check its current letter and path. Review the External Disk list rather than a local rule for a different location.

GFL will not open on another PC

Install File Lock Pro on the intended Windows computer and use the encryption password. Confirm the file is the completed encrypted output.

The local lock differs from the intended state

Select the correct item in Locking File, review Status, use Refresh, and test both Set to lock and Unlock on a sample.

A shared-folder result differs between users

Confirm the correct reachable share, client accounts, Windows permissions, and shared-folder rule. Check the actual client machines.

File Lock Pro FAQ

Can File Lock Pro hide a whole drive?

Use Local Disk > Hiding File > Hide Drive for a supported local data drive. Review the selected drive and test a noncritical target first. Use Unhide in the managed list to restore visibility.

Can I lock files on a USB drive?

Connect the USB drive and open External Disk > Locking File to manage selected files or folders. Use its Unlock control to restore access. For a separate encrypted file to transfer, use File Encryption rather than assuming a local access rule works on every other computer.

Does Protect encrypt the file?

No. Protect restricts changes such as editing, deleting, renaming, moving, or writing while keeping the content readable. File Encryption creates a separate encrypted GFL or EXE output.

What is the difference between GFL and EXE output?

GFL requires GiliSoft File Lock Pro installed on the Windows computer that opens it. EXE output runs as an executable. Open the selected output with its encryption password, choose the extraction directory, and verify the recovered contents before distribution.

What should I do before using stealth mode?

Set a recovery email, retain the management password and a working way to reopen the app, and test access before hiding shortcuts or other entry points. Clear the relevant Self Protect option when an entry point should be available again.

How can I prepare for password recovery?

Open Settings > Change Password and set an email you can access before access is lost. Keep management credentials and important source data backed up independently. Use the recovery/help route offered by the installed version or contact GiliSoft support when needed.

How do I make a hidden, locked, or protected file available again?

Select the item in its matching managed list. Use Unhide in Hiding File, Unlock in Locking File, or Unprotect in Protecting File. Check Status and normal access afterward. These controls do not restore deleted or shredded content.

Is Folder Monitor the same as Program Log?

No. Folder Monitor records events for selected monitored directories. Settings > Program Log records the available File Lock Pro program events. Both provide review and export controls, but their scope is different.

Is File Lock Pro free, and which license do these buttons show?

A Windows trial download is available; check the installed trial for its current limitations. The purchase buttons in this guide show the official checkout option at $39.95 for 1 Year / 1 PC. Review the current license choices at checkout; the lifetime option is separate.

Protect the Files You Keep on Windows

Use File Lock Pro for local access controls, encrypted GFL or EXE output, external-storage tasks, and folder monitoring.
