HELP. Had backed-up users folders (e.g. Documents, Pictures, Music) on to an external USB drive. Reinstalled Vista. Went to copy a folder from the external drive back onto the PC under the users name. A message said do you want to merge folders. said yes. The folder and files did not transfer and the existing folder on the PC is empty. Where is the folder and the files and is there anyway to get them back? I disconnected the USB drive. Thanks.
