I've been running a multisite instance since before 3.5, so the new uploads and URL structure caught me by surprise when I set up a new network.
I've been poking around for a few hours, and all the docs and posts talking about moving directories around and whatnot. I am interested in creating custom file URLs, either network-wide or per-site, in the style of pre-3.5 instances.
example.com/wp-content/uploads/sites/6/abc.png => example.com/files/abc.png
Are there acceptable or popular ways to do this that I am not aware of? Your advice is appreciated. ^_^
