Thank you very much for your quick help!
Not to be a nag though, but if i store other numerical values in the
array (like filemtime), wouldn't they be counted as well?

Would it be better to give each file a ['size'] key? In the best case,
i thought, it would be best to somehow perform the count at the same
time as doing the first loop, so you wouldn't have to run unnecessary
loop, or am i wrong?

Thanks a lot again though!!

(The '->' part doesn't have to be there, it was merely a visual
"guide" for me ...)
