A

A SQL Server Filegroup represents a logical group of one or multiple physical Files. Each Filegroup will be used as a single logical unit to allocate storage space for database tables.

A SQL Server Database must have one Filegroup defined as the Default Filegroup, or Primary Filegroup.

The Default Filegroup must contain the Primary Physical File.

If you create a new table without specifying which Filegroup to use, it will be created on the Default Filegroup.

SQL Server Filegroup information is stored in a system table called sys.filegroups. Each record in this table represents a single SQL Server Logical Filegroup.
