Hmm, not exactly I'm afraid. Should've clarified a bit more I suppose

First, this assumes all the same case (upper or lower), which isn't,
well, the case.
Second, we've got a whole dir-structure with just a few hundred files
per directory. The dir structure looks a bit like this


with the # being a digit 0-9, zero-padded. The files are about 8 - 12MB
in size and usually between 100 and 1000 files per shot, but go up to, 
and sometimes beyond, 100000 files in total for a copy-job to firewire disks

Kind regards,
