For compressed archives, it uses both Zip and Zip 64 with the choice of just about any encoding algorithm your heart desires.

It has also other useful options such as speed limitation and searching through the copy list. And as far as looks go, UltraCopier is a much more visually attractive copier replacement. (Review)

You simply right-click the file you want to encrypt or decrypt in the file listing, select the AES Crypt item, and enter your password in a little dialog box. A new encrypted or decrypted version of the file is created. Since the original file is not purged, you would need to shred it with a secure erase utility." (Review)
