Prepare a file for restricted access
Choose the actual executable, close it and confirm the permissions change.
Allow the app again
Verify your password and review the restoration result.
Plan the way back
Keep a current encrypted kit and its export-time password.
Work from a recovery copy
Open a separate data directory without replacing newer records.
Prepare for maintenance
Handle upgrades, moved files and safe uninstall in the right order.
Think through a shared session
Separate a file-access restriction from user privacy.
Map the protection boundary
Check which account, executable and copy a record actually covers.
For a New Installation
Begin with a suitable app and a known recovery plan. For a file protected by an older Free App Lock edition, check the version notes before following the 8.1.0 workflow.
