If you specify filename with the /D switch, RESTORE displays a list of the backed up files that match the name you specify. If you use the /D switch, RESTORE does not restore any files. Restoring to different drives While you must restore files to their original directory, you can restore them to a different drive. For example, files backed up from the C:\MYFILES\*.* directory can be restored to the D:\MYFILES\*.* directory.
