TOS File Encryptor

TOS File Encryptor is an application designed to protect your files with passwords. It's an intuitive encryption tool wrapped in a user-friendly interface, which can be used even by those with no previous experience in such software.

The only aspect worth noting about setup is that it cannot run unless you have .NET Framework installed. After installation, it's necessary to register (for free) with a name and email address (confirmation isn't required).

Once you reach the main app window, you can easily toggle encryption and decryption mode by clicking on the corresponding button on the left side of the window. In both cases, the steps are the same: specify the file to decrypt and destination of the new file (default is the same as source), as well as enter and confirm the password.

As soon as the task is over, you receive a popup message to let you know it's ready. Encrypted files receive the .tosl extension and can only be decrypted using this application. What's more, TOS File Encryptor gets integrated into the Windows Explorer right-click menu in order to swiftly encrypt and decrypt selected files. You can also associate it with the .tosl format to be able to open decrypted files on double-click.

In our tests, TOS File Encryptor managed to quickly encrypt and decrypt a file over 2GB without any issues. Although it leaves the original files untouched after decryption, it deleted the source file once the 2GB task was done.

Unfortunately, batch processing isn't supported, which means that you can encrypt only one file at a time. Although the encryption entry is visible in the right-click menu opened after selecting two or more files, this opens two or more instances of the application to set a password for each item at a time.

It remained low on resources usage throughout its runtime and worked smoothly on the latest Windows version, rapidly encrypting and decrypting files. Taking everything into account, TOS File Encryptor offers a simple solution for protecting files with passwords.
