What do people look for in file sharing sites?

Hi all,

I am new to this industry and started off by acquiring an established file sharing site which was pretty much left abandoned by the previous owner, but still managed to get decent traffic. As I am working on cleaning up the site (new design, new version of the script, new servers, etc.) I'd like some general thoughts around what features/mods/structures are users looking for to make a site one of their favorites. The site is running on XFS Pro 2.2.

Thanks for your help!
