EncFS is a Free (LGPL) FUSE-based cryptographic filesystem. It transparently encrypts files, using an arbitrary directory as storage for the encrypted files. Developed by arg0.net

EncFS is designed for users who need seamless file system encryption, allowing files to be encrypted and accessed as if they were unencrypted. In contrast, AES Crypt focuses on strong encryption for individual files, making it more suitable for users who need to secure specific documents rather than entire directories.
