I think the documentation for "PHYSFS_enumerateFiles" indicates that NO 
directory names will be returned in the array.

 From the docs:

Matching directories are interpolated. That is, if "C:\mydir" is in the 
search path and contains a directory "savegames" that contains "x.sav", 
"y.sav", and "z.sav", and there is also a "C:\userdir" in the search 
path that has a "savegames" subdirectory with "w.sav" [snip]

...will print:

  * We've got [x.sav].
  * We've got [y.sav].
  * We've got [z.sav].
  * We've got [w.sav].

So, here you have in the search path

and the following files:


and it clearly isn't showing "savegames" or even ".", ".." in the list 
which would of course exist on (some?) file systems.

I don't think this function is going to do what you need.  Perhaps you
could use playlists which indicate where the files are stored?

Also, another point is that the docs say:  "We only promise there will 
be no duplicates"

so if you had

C:\foo\Ace of Base - All That She Wants.MP3
C:\myMp3s\Ace of Base - All That She Wants.MP3

I *think* you would only get one song returned, even though the two 
files may be different remixes.  I haven't tested this though.
