With Folder Crypt you can password protect any Windows folder using low level encoding and standard algorithms, such as such as DES, Rijndael, Blowfish and ARC4 with keys up to 2048 bits. 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 reversibile (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. Original files and folders may be shredded. Opening, editing and listing folder contents is password protected. Full international characters support.
