I'm not sure how large the normal file sizes are but I can check the maximum file size or change it if it turns out to be a problem. It hasn't so far, though.
I'll look today, but I can't gaurantee I can find it myself as it isn't something too easily changed and normally Papaya does stuff regarding the downloads.
On a related note, if anybody does have a problem with any of the download/upload settings, please email me and I'll see if I can resolve the problem.
