How to Recover Deleted or Unsaved Cad Files?

You can tune back into your workflow after recovering CAD files with various simple methods. We have discussed detailed steps to recover deleted or unsaved CAD files below.

Through Backup (BAK) Files to Recover Unsaved Autocad Files

It is interesting to note that AutoCAD automatically creates backup files with the .bak extension. These files are created every time you save a drawing and are a safeguard against your data loss. They are often stored in the “PROGRAM” folder of your PC. Follow the steps below and find the location of .bak files.

👉Here is the step-by-step guide to recovering cad files:

First of all, navigate to the folder where your original CAD file was saved. You should find a .bak file with the same name as your original file there.
Rename the file extension from .bak to .dwg.

Now open the renamed file in AutoCAD, and your unsaved work should be restored.

使用备份文件是恢复 AutoCAD 中未保存的工作的最快方法。

通过 TEMP 文件恢复未保存的 Autocad 绘图

临时文件 (.tmp)是恢复未保存的 AutoCAD 绘图的另一种方法。这些文件是在 AutoCAD 会话期间创建的，在意外关机时可以起到救命的作用。

👉Follow these steps to recover autocad drawing using .temp files:

在计算机上的 Temp 文件夹中找到临时文件。可以在运行对话框中输入%TEMP%来访问它。

Look for files with names starting with “acad” or having the .ac$ extension.
Now rename the file extension .ac$ to .dwg.
Open the renamed file in AutoCAD to recover your unsaved work.

Recover dwg File in Autocad through AutoSave

AutoSave is a feature in AutoCAD that automatically saves your work at the interval of every 10 minutes. It minimizes the risk of data loss.

AutoSave 可确保即使 AutoCAD 意外崩溃，您的进度也能得到保存。它会创建图形的备份副本，让您在发生意外关机或软件故障时恢复工作。

Your files are saved in AutoCAD autosave location. By default, these files are stored in the Temp folder on your computer.

👉To locate and use these files for recovery, follow these steps:

AutoSave files are usually stored in the temporary folder. To find the location open AutoCAD, click on the Application menu (the big “A” in the top-left corner).
Now go to the Options button, click Files tab, and then press Automatic Save File Location to see where AutoCAD saves these files.
