In SQL Server data is stored using two physical files:
- (.mdf) extension which contains the data.
- (.ldf) extension which contains log.
Log file size increases very rapidly and depend on the operation performed on the data. After a long time period this file becomes too large. When log file is too large it takes time to perform some operations like ( attach , de-attach, backup, restore … etc ).
