What Is AutoCAD Bak File?

Understanding AutoCAD BAK Files

AutoCAD generates BAK files as a backup measure when you save your drawing files. These backup files are crucial for ensuring that you have a copy of your work in case of unexpected issues like corruption or accidental deletion of the original file. The BAK file carries the same name as your drawing but has a “.bak” extension at the end, making it identifiable as a backup version.

The Purpose of BAK Files in AutoCAD

Each time an AutoCAD user saves a file, the program automatically creates a BAK file. This file acts as a snapshot of the drawing prior to the latest save, ensuring that previous iterations of your work can be retrieved if needed. The BAK file is particularly beneficial in settings with frequent edits, allowing users to revert to earlier designs without any hassle.

Is It Safe to Delete BAK Files?

BAK files are essentially backup copies; therefore, their deletion is generally safe as long as you have confirmed the integrity of your main drawing files. If you decide to delete a BAK file, ensure that the corresponding DWG file is functioning correctly and is free of corruption. If uncertain, it may be wise to move the BAK files to a separate folder instead of immediate deletion, allowing you to restore them if any problems arise later.

What Happens If You Delete a BAK File?

When a BAK file is deleted, you lose the ability to revert to the previous version of your drawing unless you have other backups. It’s advisable to keep backups in different formats or locations to avoid losing crucial work. If you’re hesitant about deleting a BAK file, consider transferring it temporarily into a different directory to monitor any potential issues that could occur after its removal.

Recovering an AutoCAD BAK File

1. Locate the BAK File: Use Windows Explorer or File Explorer to find the BAK file you wish to recover.
2. Rename the File: Right-click on the BAK file and select the “Rename” option. Change the extension from “.bak” to “.dwg”.
3. Open the File: After renaming, double-click the file to open it in AutoCAD as you would with any DWG file.

Converting a BAK File

To convert a BAK file back to its original format:

1. Access Windows Explorer: Right-click the Windows “Start” button and open Windows Explorer.
2. Adjust Folder Options: Go to the “Tools” menu and select “Folder Options.” Under the “View” tab, deselect the “Hide Extensions for Known File Types” box to see file extensions.
3. Rename: Find the BAK file, right-click, and rename it, changing the “.bak” extension to the appropriate format.

Locations of BAK Files

The location of BAK files is typically in a default directory, often found in “C:\Documents and Settings[User Name]\Local”. It is generally advisable to check your system settings or AutoCAD preferences to locate where your specific BAK files are stored.

Removing the BAK File Extension

If you want to change a file from a BAK to another format, simply rename it, removing the “.bak” extension, and replacing it with the desired extension, such as “.doc” or “.pdf,” based on the file type you wish to access.

Steps to Delete BAK Files on Windows 10

1. Open Control Panel: Go to the Control Panel from the Start menu.
2. Navigate to System and Security: Click on “System and Security,” then select “System.”
3. Access System Protection: On the left sidebar, find and click on “System Protection.”
4. Configure: Click the “Configure” button to access system protection settings.
5. Delete BAK Files: Look for the delete option and click on it to remove unnecessary BAK files.
6. Apply Changes: Confirm by clicking “Apply” and “OK” to complete the deletion process.

Programs That Can Open BAK Files

Apart from AutoCAD, BAK files may also be opened using various applications, notably Microsoft SQL Server Management Studio, which uses these files to restore databases.

Converting BAK Files to PDF

Should you need to convert a BAK file to a PDF, ensure you have a compatible reader. Open the file and select the “Print” option, then choose a PDF printer to create a virtual PDF.
