| | | ID3 - Does the file have an ID3 tag?
| | Memo - Does the file have a MEMO in the beginning (')
| Selected - remembers wether the file was selected or not...
Present - was the file valid last time the MPO file was loaded?

Example of a file description byte:
10100000b
This one contains a Memo in the beginning and was present when the MPO file
was saved to disk.


(') Memo is a text file inserted in the beginning of an MP3 file containing every char
but FFh. If it contains FFh, almost every Mp3 player goes nuts... (Mp3 stream header and bla bla bla...)
The Memo can be found in most beatforge releases. Note! This has nothing to do
with ID3v2 altough it works almost the same way...
