How To Open Bak Files In AutoCAD?

Understanding BAK Files in AutoCAD

BAK files serve as backup files for AutoCAD drawing files, specifically those with the .dwg extension. When you create or edit a drawing in AutoCAD, the software automatically generates a corresponding .bak file to safeguard your work. This innovative feature allows users to recover their progress in the event of a software crash or unintentional closure.

Steps to Open a .BAK File in AutoCAD

1. Locate the BAK File:
Begin by navigating through File Explorer to find the desired .bak file on your computer. This file is usually located in the same directory as the original .dwg file.

2. Rename the File:
Right-click on the .bak file and select the ‘Rename’ option. Change the file extension from .bak to .dwg. To do this, simply erase ".bak" and input ".dwg" at the end of the file name. If you can’t see the file extensions, you may need to adjust your Folder Options to reveal them.

3. Open the Renamed File:
Launch AutoCAD. Use the ‘Open’ dialog box to locate and select the newly renamed .dwg file. Click ‘Open’ to access the drawing as if it were any standard AutoCAD file.

How to Find AutoCAD Backup Files

Finding backup files can be achieved through different methods based on your operating system.

  • For Windows Users:
    Open AutoCAD and navigate to the ‘Files’ tab found in the Options dialog. There, you can explore the ‘Automatic Save File Location’ to determine where backups are typically stored.

  • For Mac Users:
    Within AutoCAD, access the Preferences menu under the ‘Application’ tab to view the directory for autosave files. These paths will guide you to your backup locations.

Converting a BAK File to PDF

To convert a BAK file to a PDF, you first need to open it in a relevant viewer compatible with BAK files. Once opened, use the print function and select a PDF printer as the output option. This process allows you to create a PDF version of the original drawing with ease.

Deleting and Managing BAK Files

It is safe to delete .bak files if you are sure that you no longer need them. These files are created automatically during the saving process, so if your drawing is properly saved, the BAK files can be removed without worry. For caution, consider moving them to a temporary folder and monitor whether any issues arise.

Disabling the Creation of BAK Files in AutoCAD

If you prefer to not have AutoCAD generate BAK files, you can disable this feature:

  1. Right-click in the drawing area and choose ‘Preferences.’
  2. Navigate to the ‘Application’ tab.
  3. In the dialog box presented, uncheck the ‘Automatic Save’ option.

This action stops the creation of BAK files from that point forward.

Frequently Asked Questions

1. Can BAK files be opened in programs other than AutoCAD?
Yes, BAK files can be opened in various text editors or by renaming them to different formats, but their primary use is within AutoCAD.

2. Is there a way to restore a lost AutoCAD drawing from a BAK file?
Absolutely, simply locate the BAK file, rename it to .dwg, and open it in AutoCAD. It should contain the last saved version of your drawing.

3. Are BAK files essential to keep for future AutoCAD projects?
They are not strictly necessary for ongoing projects if you regularly save your work. However, they can be a useful fallback in cases where previous versions or saved states are required.
