If your PC is being used by your friends, then probably you might want to protect your personal files in one of the drives in Windows. DriveLocker is a freeware tool which allows you to lock any drive and subsequently hide it from any users. The application is portable and once you open the tool it lists all the drives and you can select the drives you want to lock and hide.
The program is lightweight and very easy to use. Just select the drive you wish to lock or hide and press apply. Then, it will no longer be available to anyone else.
Important: Make sure that you don’t lock and hide the Windows installation drive.
