Free PHP-based download management system?

[Teancum]

So I've been looking to integrate a downloads system, and our current setup is all PHP. The long and the short of it is this:

• PHP-based
• Operates as a subdirectory of the current site (so I can quickly edit the header for a link to the download section)
• Allows users to simply put in a link to their download (Mediafire, Google Drive, Dropbox, etc) -- to save bandwidth
• Allows linking to external screenshots
• Basic sorting and search features
• Free

I've been digging through several different CMS sites for their extensions, but I'm wondering if I'm just not phrasing what I want correctly and so I can't find what I want, or if there's just a simple "downloads only" PHP section. I'd love to have something like JKHub's, but it looks to be IP.Board, which is costs. Essentially what it comes down to is how can I have a files section that uses external bandwidth for the actual files, and doesn't cost anything.

 

I ask here mostly because I know that a lot of custom work has been done on JKHub, and so I figured there might be some knowledge of third-party apps.

 

Thanks!

I'm sure there are plugins for WordPress that can do this. Finding something free in general will be difficult though, I'm sure.

Maybe we'll just run WordPress and I'll modify a files plugin. Thanks!
