Ah, you meant the working copy size in that other thread. Then, yes, it reduces local copy size if you have checked out root, but then I don't see a reason to check out root in the first place.NOTE: This will decrease your local copy's size by at least 2 GB (if you have the root checked out, which all DLL modders probably do), and the old branch was something I made a while ago that never came to anything, so I see this as a good decision.
