Folder Crypt 3.1.2040

The program performs a true bit per bit encryption of your data. All you have to do is to supply a password or passphrase, which will be turned into a strong password by an hashing function. The encryption process is not reversible (you can decrypt the folder only if you know the correct passphrase). Your encrypted folder will appear as a .crypt file in place of the original folder...
