If only it was that simple... it just needs to be all in one directory for another program that parses them (that I didn't write).

Like I said, ls on Linux takes about 10 seconds for all those files, so it still leaves me guessing.

I'm also thinking MD5 is a bit of an overkill on 15000 * rather short filenames, a simple rotating hash would be quicker. And more efficient.
