Two days before I have been upgraded my computer with Windows 7 from Windows XP service 3. Before doing installation I have back up all the files using file and setting transfer wizard of the Windows XP on the external hard disk of mine. After finishing the installation I have been launched the file transfer Wizard of Windows 7. But I have found that it was unable to open back up files. Well all the backup files are either dat files which are having a status file in to the folder USMT2.UNC. Anyone having idea regarding this matter will be highly appreciated. Thanks a lot in advance.
