Thanks for this. Unfortunately, it won't always be mp3s.
Peace Mike

Hi everyone... I catalog my external media using the 'tree' command and this generates a file such as the one attached. Does anyone know of a bundle developed to allow folding for this?

Hmm, I don't think this is possible given the current folding architecture. Hopefully it will be possible with the new parser features being added for 2.0.
To figure out whether a line should actually start a folding you really need to be able to look ahead to the next line, and I think you can't do that in TM. (yet?)
But if your actual data is a bunch of directories of MP3 files, a simple little language which sets
foldingStartMarker = '^(| )*|-- .*(?<!.mp3)$'; foldingStopMarker = '^(| )*`--';
does more or less the right thing. The "negative lookbehind" is the hacky heuristic to decide whether a line starts a folding or not: it will break if there are empty directories, if any file name doesn't end with .mp3, or if any directory name does. Giving the -F flag to `tree` will disambiguate the naming things (use "/$" instead of "(?<!.mp3)$", but won't fix the problem with empty directories.
One of the things I really like about TextMate is that such customizations are quick enough to be economic even for grotty single-use "languages" like this one.
