USB Security for Windows

Summary of the application

USB Security, created by Kakasoft, locks a flash drive so only someone with the correct password can access its files. Once protected, the drive’s contents are hidden and ordinary file browsing will only reveal the program’s icon. Attempting to open the drive prompts for a password to unlock it.

Installing and activating the protection

1. Plug the USB flash drive into your computer. If no drive is connected, the installer will ask you to insert one.
2. When the program detects available removable drives, select the target device from the list shown.
3. Enter a password (you may also add an optional hint) and confirm.
4. Click the Protect button to apply the lock to the chosen drive.

After these steps, the drive will be secured and require the entered password to view its hidden contents.

How the locked drive behaves

• Only the USB Security icon will be visible when the drive is locked; the actual files remain hidden.
• Clicking the icon opens the program window and prompts for the unlock password.
• Unlocking lets you view and edit files, but the protection is not restored automatically when you eject the drive — you must run the application and lock the drive again to hide the contents.

Using a locked drive and portability

• The protection is stored on the USB device itself rather than on the host computer, so you can use the same locked drive on other machines without installing the application on each PC.
• You can still copy files onto the drive even while it’s protected; newly copied items may appear alongside the security icon but previously hidden files remain concealed.
• Sharing the drive is safer because others cannot access hidden data without the password.

Notable advantages

• Fast setup — installation and protection can be completed in a minute or two.
• Simple interface — few controls, making it straightforward for anyone to use.
• Optional password hint — helps recover access if you forget your password.
• Keeps files private while allowing the drive to remain functional for routine file transfers.
