What Is the File Extension Ldf?

Databases are used by companies to store vital information about a variety of things, including customers, inventory, and accounts. There are a number of files associated with databases, including .ldf files.

  1. Background

    • A file with the .ldf file extension is created by the Microsoft SQL server, which is a system that saves a company's database information. Authorized users from throughout the company have the ability to retrieve information from the SQL server from the computers at their location.

    Identification

    • A file with the .ldf file extension is known as a server transaction log.

    Function

    • A file with the .ldf file extension contains a record of all changes made to the information saved on the server. The .ldf file extension serves as a marker, allowing an administrator or technician to locate the file on the server when it is needed.

    Features

    • The .ldf file contains the date and time of changes, the details of the changes, and information about the user who made the change or the terminal or computer the change was made from.

    Benefits

    • If an error is made or an unauthorized change occurs with information saved to the database on the SQL server, the log can help determine who made the changes and when.
