=== Notes and Comments === 

* The filename bytes are XOR with the key in the header.<br>
* If the filename length is not a multiple of 4 bytes, the left over bytes are not XORed<br>
* The first 20 bytes of the file data (for each file) is XORed with a single byte found in the directory, which is different for each file. The remaining bytes of the file data are to be read as normal.
