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:
- 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.
- 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.
