Overview
The RESTORE FILELISTONLY option allows you to see a list of the files that were backed up. So for example if you have a full backup you will see all of the data files (mdf) and the log file (ldf).Explanation
This information can only be returned using T-SQL there is not a way to get this information from SQL Server Management Studio. Although if you do a restore and select options, you will see some of this information in SSMS.
The RESTORE FILELISTONLY option can be simply issued as follows for a backup that exists on disk. If there are multiple backups in one file and you do not specify "WITH FILE = X" you will only get information for the first backup in the file. To get the FILE number use RESTORE HEADERONLY and use the "Position" column.
