So I restore my system from a backup (Acronis True Image is a life saver). But all my program settings in "AppData" are out of date. No problem. I have a daily backup of those files. So I just drag everything over from my external hard drive. Vista tells me that there's already a folder called "Foobar" and I just tell it to copy everything anyway and I check the "Do this for the next xx conflicts" box. Everything gets copied. Works great.
Then I try the same thing with Windows 7. It silently creates a folder called "Foobar - Copy" and puts everything there. Since the Foobar program expects it's files to be in a certain location -- not a folder called Foobar - Copy, this obviously creates a problem. Not to mention the fact that it did the same thing to the other 27 folders that were copied.
Nice work screwing up one of the really useful features in Vista.
