I was looking at my Application Data folder to determine where I should go to back up/restore my User Files folder if need be, and noticed that I have several copies. I have had this PC a while, and have gone through 5 upgrades and all the previous user folders are still there (eating up a little disk). I assume it is ok to delete the old ones once I’m happy with the upgrade? Also, in the current version there is a folder called ATResults that seems to contain yet another copy of the User Files folder - what is this? Is that only created/used during the install/upgrade?
