TrueCrypt creates TrueCrypt volume containers (encrypted files) where you store your secret data. Later you can mount it like any other volume, by providing the password/keyfile. The good thing is that it works "on the fly", in other words, it encrypts/decrypts the data in RAM before making changes to disk, as you write/read files to/from the volume. It can also encrypt full partitions/drives. For the documentation, see: http://www.truecrypt.org/docs/

As you said it is a software for encryption, for more information you'd better have a look at http://www.truecrypt.org/docs/.
