File Locker is a small software application developed specifically for helping you encrypt private files with the aid of a master password. The program makes use of the RC4 encryption algorithm.

It takes nothing more than a simple and quick installation process in order to gain access to the GUI. The layout looks easy to decode so you are not going to spend a lot of time tweaking the dedicated parameters.

A help manual is not available. However, you can manage to configure encryption tasks on your own. A wizard-like approach is implemented for helping you encrypt or decrypt files by simply following the step-by-step instructions.

File Locker offers you the possibility to set up a master password when you run it for the first time. The master password is needed to gain access to the program’s interface.

What’s more, you are allowed to import files that you want to encrypt or decrypt using only the built-in browse button (the drag-and-drop support is not implemented). The tool lets you clear the list with items with a single click.

The encrypted files have a different file extension so they cannot be opened with a dedicated program. In order to decrypt items successfully, you simply need to specify the password-protect file. File Locker does not let you set up individual passwords for each file that you want to lock. It makes use only of the master password.

Tests have pointed out that File Locker carries out encryption/decryption jobs quickly and without errors. It does not eat up a lot of CPU and memory resources so the overall performance of the computer is not hampered.

To sum things up, File Locker provides a simple software solution for helping you password-protect confidential files on the fly. It can be tweaked by less experienced users and professionals alike.
