Restore from file
To restore individual files to a specified destination using an external map file, enable this option. The map file provides the list of files to be restored and the destination to which the files are to be restored. (See Restore Data Using a Map File in Books Online for detailed information.)
Use the space to enter the path and name of the map file, or use the Browse button to locate and select the appropriate map file.
