Yes. Connect the USB drive, open External Disk, then choose Locking File or Hiding File according to the result you need.

What is the difference between GFL and EXE output?

GFL is File Lock Pro encrypted output. EXE output is packaged as an executable. Test the chosen output on the intended Windows environment before distribution.

What should I do before using stealth mode?

Set a recovery email, remember the access method and master password, and test the setting before hiding File Lock Pro shortcuts or entry points.

How can I prepare for password recovery?
