An AutoCAD file is a digital drawing in 2D or 3D produced using AutoCAD software. Used by architects and engineers to plan projects such as buildings and machinery. These files come in formats like DWG and DXF and are essential for storing and sharing design information.


However, it can be annoying when you find that AutoCAD files are unsaved deleted, or corrupted due to various reasons. Don’t worry, this article will tell you 5 effective ways to recover AutoCAD files.

Way 1. Recover Unsaved AutoCAD Files from Backup

Restoring files from backups after data, unsaved, deletion, or loss is always a good choice. If you've lost a saved AutoCAD file, you can often retrieve it from the automatic backups stored in the same folder. Here's how to recover AutoCAD file from backup file:

  • In this case, regular backup of files becomes particularly important in our daily lives. If you don't have a backup, move on to the next method.
  • To avoid losing any data, this free backup software likeAOMEI Backupper Standard can automatically create copies of your files.

1. Find the folder where your AutoCAD files are stored. And look for a backup file with a .bak extension.


2. Copy and paste the .bak file to a safe folder (in case it will be overwritten).

3. Right-click the copied file, choose Rename, and change the file extension from .bak to .dwg. Click Yes to confirm the change.

4. Double-click the .dwg file to open it in AutoCAD.

Way 2. Recover Unsaved AutoCAD Files from Autosave

Because AutoCAD has a built-in Autosave feature that periodically saves your work. You can recover AutoCAD dwg files using this feature. Here's how:

1. Open AutoCAD and type options in the Command line. Select Options.

2. Go to the Open and Save Check if the Automatic save box is selected. It's advisable to set the Minutes between saves to 5 or less.

Automatic Save

3. Go to the Files, expand the Automatic Save File Location, and note the location where autosaved files are stored. For example, C:\Users\User Name\AppData\Local\Temp


4. Copy the autosave file path and paste it into Windows File Explorer. Press Enter to open the AutoSave file folder.

5. If you can't find the autosave file, make sure to show hidden file extensions. To do this, go to File Explorer > View > Uncheck Hide extensions for known file types > Click OK.

6. Look for the CAD autosaved file with a .sv$ file extension. Copy it and change the extension of the copied file from .sv$ to .dwg.

Change Extension

7. Double-click the .dwg file to open it in AutoCAD.

Way 3. Recover Deleted AutoCAD Files Using Recovery Software (Faster)

If you've mistakenly deleted or lost your AutoCAD files, including both .dwg files, there's still hope for AutoCAD .dwg/.dxf files recovery. The first thing is to check the Recycle Bin to see if you can restore the deleted folder or file from Recycle Bin.

If it's not there, you can resort to a reliable data recovery solution. I strongly recommend using powerful AutoCAD files recovery software - MyRecover due to the following advantages:

Way 4: Recover Corrupted AutoCAD Files Using Drawing Utilities

Sometimes after successfully recovering AutoCAD files, the files may be corrupted or you cannot open them in AutoCAD. You may encounter the "Drawing file is not valid" error message when trying to open a .dwg file, you can use AutoCAD's Drawing Utilities to repair the file:

1. Click the AutoCAD icon at the top-left corner of your screen. Then, select Drawing Utilities>Drawing Recovery Manager.


2. Expand the drawing node within the Drawing Recovery Manager window to access the active drawing before the crash occurs. Double-click the corrupted file you want to recover.

3. If this doesn't work, go back to step 1. Then, select Audit If the file is still corrupt, a message will appear asking you if you want to continue.


4. Choose Yes or enter Y in the command window to initiate the repair process. A diagnostic report will be displayed during the process. Just wait for it to finish.

Choose Yes

5. When the repair is successful, save the drawing file when it opens.

Way 5: Recover Corrupted AutoCAD Files Using RECOVER Command

If the previous method doesn't work, you can try using the RECOVER command in AutoCAD:

1. Open a new DWG file in AutoCAD and enter RECOVER in the Command line. Select the corrupted file and AutoCAD will attempt to recover and open it.

2. Open a new DWG file and run RECOVERALL command. Select the corrupted file and AutoCAD will attempt to recover and open it.

3. Open a new DWG file and run INSERT command. Choose the corrupted file to see if it will be inserted. If not:

  • Run EXPLODE and select the inserted block
  • Run AUDIT and PURGE commands
  • Click SAVES to create a new DWG file

4. Go to C:\Windows\Temp and look for files with an SV$ extension. If you find a similar file with the same name as the corrupted .dwg file, rename it to .dwg and see if it opens.

5: Try opening the corrupted drawing using DWG Trueview. If successful, convert it to an older DRW version and try opening it again.
