.BAK File Association 2
A BAK file is a backup of another document or file, commonly created automatically by software programs or by the operating system. It typically contains a copy of the original file and can be restored to the original by replacing the .bak extension with the original extension.
Often BAK files are created by simply appending .bak to the original filename. For example, document.doc may have a backup file document.doc.bak.
NOTE: An example program that uses the '.bak' extension is AutoCAD. Windows may also create BAK files for the System.ini and Win.ini files.

.BAK File Association 7
A BAK file is a backup of a Microsoft SQL Server database. It contains a copy of all or some of the files included within the database. BAK files are created using SQL Server Management Studio, Transact-SQL, or Windows PowerShell.
Database administrators use Microsoft SQL Server to store data within relational databases that reside on one or more servers. Because servers can fail and databases can become corrupted, administrators often create backups of their databases and store them on separate servers. That way, administrators can easily replace their original database with its backup if an issue arises. Database backups are saved as BAK files.
Sometimes, administrators create backups that contain only part of a database. These backups, known as differential backups or partial backups, are also saved with the .bak extension.
How do I open a BAK file?
You can open a BAK file and use it to restore a SQL Server database in Microsoft SQL Server Management Studio, which is included in Microsoft SQL Server. To do so, follow the instructions included in Microsoft's online SQL documentation.
