  • MDF
  • NDF
  • LDF

MDF: MDF is a master database file. It stores the users data in the form of rows, columns, fields, indexes, views and tables. MDF file can be loaded to database using Microsoft SQL Server.

NDF: A file with .ndf extension is a secondary database file used by SQL Server. It is s secondary storage file because SQL Server stores user specified data in primary storage file known as MDF.NDF file is optional and is user defined to manage data storage.

LDF:LDF is log file which stores all the transactions maintained by SQL Server. It can help you fetch any time log activity performed by users.
