You should always store large amounts of files you need to use in a single file/hashtable/whatever.
If you have a lot of mp3s then a hashtable would be best, repeatedly accessing a single file can be slow as well, especially with $read instead of file handling commands.
* tidy_trax thinks a $findfilecall() (Like $dllcall() and $comcall() - multi-threaded) would be nice.
