His wiki has 3200 pages, 900 is just the count of article pages. The database dump was already suggested, so I don't see why we're going back to Special:Export now. Special:Export doesn't dump files either.

By my knowledge you can't export files, so you will probably need to create a script that does this for you. It's pretty clear you are trying to move away from Wikia, though, so you may not get a lot of help here.
