What is a .NDF file extension?

.NDF file extension is created by Microsoft. .NDF has been classified as Database Files.

.NDF is SQL Server Secondary Database File

Secondary database file used by Microsoft SQL Server; created when the primary .MDF database becomes too large (such as when there is no disk space left); may also be manually added to the SQL Server File Group to distribute data between the two files.

NDF files are typically stored on a different hard disk or partition than the primary database file. Each NDF file uses the same filename as the corresponding MDF file, such as "mydb.mdf" and "mydb.ndf." Also, the NDF file cannot be opened by SQL Server without the MDF file attached.
