Please do remember, find a easy folder to save the wallet file that the user need to back up.
Don't put it at %APPDATA%/bitcoin anymore.For geeky it's easy, but for average users it's difficult!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I suggest to let the user chose where to put the wallet file, and the software just recommand some simple folder, like D:/bitcoinwallet/ and in this folder, don't put those rubbish file in it, just the wallet!!!please!
