The Lock - Version 1.2 SUPPORT FOR ALMOST ANY FILEThe Lock is fully capable of encrypting any file type, including images, video, audio, documents, zip files, even programs. The only real limit in its capability is the file size - 4GB, still enough for 99.9999% of files.SECURE ENCRYPTIONThe Lock uses a number of complex data encryption methods to lock your file, all based on the password you enter. Every method is used on your file at the same time, so you can be safe in the knowledge that your data is safe. EASY-TO-USE INTERFACEEven though The Lock is a complex encryption program, it is also one of the easiest to use. You can use The Lock's own interface, or you can lock files with a simple right-click in Windows itself.AUTOMATIC RE-ENCRYPTION(New for version 1.1)When you unlock a file, you will now be asked if you want to open it. If you do, you will be asked if you want to re-lock the file when you close it, without the need to enter the password again.
