With Folder Crypt you can password protect your Windows folders using low level encoding and standard algorithms, such as DES and Rijndael. The program perform a true bit per bit encryption of your data. All you have to do is to supply a password or passphrase. 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. Even to list the files in the encrypted folder you must know the password.
