    SQL Server Database Files
    Database File Types

    Database files are categorized into three types:

    • Primary data file. This file is the starting point of the database. Every database must have one, but only one, primary data file. Primary data filenames usually have an .mdf extension.

    • Secondary data files. These files are optional and can hold all data and objects that are not on the primary data file. A database does not have to have secondary data files, but may have multiple secondary data files. Secondary data filenames usually have an .ndf extension.

    • Log files. These files hold all the transaction log information used to recover the database. Every database has at least one log file. Log filenames usually have an .ldf extension.
