LDF File Format

Microsoft SQL Server log file

LDF is a file extension for a log file used with Microsoft SQL Server. LDF files contain logging information for all transactions completed by the server. LDF files are used to time stamp any transactions to the SQL Server database, allowing the SQL database to be easily recoverable in the case of data loss.

MIME type: application/octet-stream

The LDF file extension is also used for library definition files for Geoworks Glue.
