Dec Enc encrypts any file you throw at it, any size can be handled and does not take huge amounts of memeory to run - bout 1.5 MBs at most of free RAM is all that is needed to encrypt any file, and less than that if the file is smaller.
Dec Enc uses a byte array to read data from a file and then encrypts the file and writes the array out to a file.
Most other programs I have seen use strings to store data, which are limited in how much they can store.
Although Dec Enc uses XOR encryption, it could be made better with another encryption technique.

Assumes
If you intend to use file compression on a file and encrypt it, compress the file first and then encrypt as this will yield better results.
