You can protect folders on your hard drive, USB external and removable drives. If you install Password Protect USB right on your removable drive, you can protect/unprotect folders at any computers your drive is connected to. To unlock your folder, you do not need to run the program: just double-click the folder in the right pane of Windows Explorer and enter your password.
The program was designed with safety in mind. For example, if you try to protect a system folder, which is crucial for Windows to run properly, Password Protect USB displays a message explaining why you should not do that.
