What is an AutoCAD bak file?

What is an AutoCAD bak file?

An AutoCAD .bak file is a backup copy of an AutoCAD drawing file (.dwg) created automatically by AutoCAD as a precautionary measure to prevent data loss.

Usage: BAK files serve as a safety net. If the original .dwg file becomes corrupted or experiences issues, you can potentially recover data from the corresponding .bak file to avoid data loss.

Examples of Use:

  1. Data Recovery: If your .dwg file gets damaged due to a software crash or other issues, you may use the .bak file to restore the last saved version.
  2. Accidental Deletion: If you accidentally delete important data from your drawing, you can sometimes find that data in the .bak file.

AutoCAD .bak files are a valuable precautionary feature, but they are not intended to replace regular manual backups of your work.
