How to open bak file in autocad- AutoCAD Backup and Autosave

Backup (.bak) Files
Drawing backup files are typically created every time that you manually save a .dwg file. By default the file will be saved in the same location as the .dwg and will have the same name as the drawing but with a .bak extension, such as, site_topo.bak. A backup file is an exact copy of the drawing file prior to the last save. As such, backup files are always one version older than the currently saved drawing. Only one backup file is retained at a time so newly created backups will always replace older backups of the same name.

MOVEBAK Command

Included in the AutoCAD Express Tools is the MOVEBAK command which allows you to specify an alternative folder for your bak files when created. If you want to keep all your bak files in a single location—as opposed to keeping them in the same folder as the associated drawings—you can use MOVEBAK to specify another folder and all bak files will be automatically moved there when created. Enter “.” as a value to reset AutoCAD to the default behavior.

Note: MOVEBAK is only available in Autodesk products that include the AutoCAD Express Tools. The MOVEBAK command has not been updated in recent years so it may not support paths with embedded spaces.
