hi,
you can use this syntax to view the file backup information
RESTORE FILELISTONLY FROM DISK = N'C:\restore\restore.bak'
if you need more info you can use those syntax
RESTORE HEADERONLY FROM DISK = N'C:\restore\restore.bak'
RESTORE LABELONLY FROM DISK = N'C:\restore\restore.bak'
RESTORE VERIFYONLY FROM DISK = N'C:\restore\restore.bak'
