    I'm not sure if this information I'm sending is true (I don't have any AIFF
file), but it's here... check it out, it's been taken from

If you notice any mistakes or omissions, please let me know!  It is only
with YOUR help that the list can continue to grow.  Please send
all changes to me rather than distributing a modified version of the list.

This file has been authored in the style of the INTERxxy.* file list
by Ralf Brown, and uses almost the same format.

Please read the file FILEFMTS.1ST before asking me any questions. You may find
that they have already been addressed.

contained in this list to the best of my ability, but I cannot be held
responsible for any problems caused by use or misuse of the information,
especially for those file formats foreign to the PC, like AMIGA or SUN file
formats. If an information it is marked "guesswork" or undocumented, you
should check it carefully to make sure your program will not break with
an unexpected value (and please let me know whether or not it works
the same way).

Information marked with "???" is known to be incomplete or guesswork.

Some file formats were not released by their creators, others are regarded
as proprietary, which means that if your programs deal with them, you might
be looking for trouble. I don't care about this.
