I run a few sites with file download sections and my current set of scripts that were quickly written a long time ago when the downloads area was much smaller simply isn't cutting it. Does anyone have any recommendations on an open source PHP solution for hosting files? I know there are a couple out there but I'm looking for some advice from someone already using one. I want to have some of the bells and whistles like file ratings, top downloads, version tracking, comments. Anyone know a good solution?
