If you're allowed to alternate between two compression
methods, then the way you decompress
music.mp3.zip.zip.tgz.zip...........tgz.zip.tgz
is to output 0 each time zip was applied and 1 each
time tar/gz was applied.

You may be able to take some shortcuts in some
cases, e.g. anything beginning with "movie.flv"
almost certainly contains a cute kitten video.
(Unless it's found inside an encrypted disk
partition, in which case it contains porn.)
