RESTORE FILELISTONLY – How many Files are in backup set?
Sometimes prior to restoring a backup we need to see how many files will be created if we restore a backup and on what location those files will be created. For that we can use RESTORE FILELISTONLY command to get list of files.
RESTORE FILELISTONLY FROM DISK=N'e:\location-of-backupset';

The above command does NOT restore the backup but will just only list the info about files that where SQL Server is going to create the data and log files and of how much size, their logical and physical names.
If “PhysicalName” location is not available in your restoring-server you can use WITH MOVE command to explicitly tell SQL Server that where these files should be created.
