How to restore dwg from bak file

The bak file is the file format used in AutoCAD software to back up DWG files. When we accidentally delete or damage the original DWG file, we can use the bak file to restore it. This article will introduce how to restore dwg files using bak files.

1. Find the location of the bak file and source DWG file
First, we need to find the location where the bak file and source DWG file are stored. Normally, the bak file will be saved in the same folder as the DWG file. If you can't find it, try searching for the .bat file in Windows Explorer.

2. Restore DWG files
The following are two methods to restore DWG files:

Method 1: Double-click to open the bak file
If your system has been associated with automatic CAD software, then you can directly double-click to open the bak file. This will automatically restore the bak file to a DWG file and open it in AutoCAD software.

Method 2: Use AutoCAD software to restore

1. Open the AutoCAD software.
2. Find the "File" option in the top menu bar of the AutoCAD software and click the "Open" option in the drop-down menu.
3. In the open window, change the file type to "Bak Files" or "All Files" and browse to the folder where the bak file and the source DWG file are stored.
4. Select the correct bak file and click "Open".
5. AutoCAD software will automatically restore the bak file to a DWG file and open it.

It should be noted that if the source DWG file already exists in the target folder, AutoCAD software will prompt you whether you want the restored DWG file to overwrite the source file. After confirming that there are no important changes, you can choose to overwrite the source file.

3. Additional precautions

1. Maintain the consistency between the source DWG file and the bak file. In order to restore smoothly, ensure that the source file and bak file have a one-to-one mapping relationship, that is, each DWG file has a corresponding bak file.
2. Back up DWG files regularly. To avoid data loss, it is recommended to back up DWG files regularly and store bak files in a safe location.

Summary
Through the above steps, we can easily restore DWG files using bak files. Whether you double-click the bak file to open it directly, or use AutoCAD software to restore it, you can quickly recover our accidentally deleted or damaged DWG files. However, we still need to pay attention to data security and regularly back up important DWG files to avoid unnecessary losses.
