LockMyDrive is a program designed to hide and encrypt files on various storage devices. It doesn't require installation, disk formatting and computer restart. To start using the program, simply download the Registrator (.exe file) and set up LMD on your device. Then, run the .exe file from your registered device and LOCK/UNLOCK your files in one click. In case of an external storage device (HDD/SSD drive, memory card, Flash drive), you can use it at office or at your friend's place and hide files with LMD without administrator rights. At that, your device remains fully functional and can be used by guest users for copying new files while your files will remain invisible and nobody will even guess that they actually exist.
