You'd think this would be the kind of functionality that was built into each of the various digital distribution platforms. But as it turns out, they actually leave an awful lot of junk lying around on your hard drive.
And it's not just Steam. Uplay, Origin, GOG Galaxy, Desura — they all do it. So someone's trying to get a tool Greenlit that will clear all that junk out.
It's called Steam Cleaner, a plain name for a fairly plain tool. It's designed to wipe out the following:
Additional software packages; Old logs; Cache; Unused user profile files; Leftover game files.
Of course, it's not the first application to offer such a service. Readers might be familiar with the TikiOne Steam Cleaner from Jonathan Lermitage that efficiently performs the same service, and it's available to download for free via Github now.
But the main advantage with Steam Cleaner is its support for the other distribution platforms. Battle.net, Desura, Origin, GOG Galaxy, Uplay and Steam are all supported, and you can download a beta version of the program through the Dropbox links posted on the Steam announcements.
