How Do I Recover An AutoCAD Autosave File?

"OK, this is the deal. Yesterday, I finally finished designing a bridge measure graphic with precise figures. And I remembered that I saved it carefully on my PC. However, this morning, when I tried to show my colleague the .dwg file, it wasn't in the folder where I used to safe AutoCAD drawings. How do restore the lost .dwg file in AutoCAD?"

It's no longer a new issue that AutoCAD users lost their long-time drawings without saving or CAD .dwg files corrupted on their computers. If you are having a similar problem that you lost AutoCAD files or your CAD files corrupted in PC, don't worry.

Here we'll provide you with reliable and effective methods to recover lost CAD files and show you how to repair the corrupted .dwg files.

Method 2. Recover Lost CAD File from Backup - .BAK File

When you lost a saved CAD file or an editing CAD file, you may also go to the CAD folder on your PC and you can try the below steps to restore lost CAD file from its .bak file:

Step 1. Go to the local folder which you use to store the CAD files, and locate the backup file with .bak extension.

Step 2.Copy and paste the .bak file in the folder and change the file extension of the copied file from .bak to .dwg, hit Enter to continue.

Step 3. Click "Yes" to confirm that you want to switch the .bak file to .dwg. Then you can double-click the DWG CAD file in AutoCAD.

There, your lost or unsaved drawing is back and you can save to keep this file on your computer by then.

Step 4.If you can't locate the autosave file, show hidden file extension by opening Options in File Explorer > View > Uncheck "Hide extensions for known file types" > OK.

Step 5.Locate the CAD autosaved file with .sv$ file extension, copy it and change the extension of the copied file from .sv$ to .dwg, hit Enter to confirm.

Step 6.Then you can double-click the DWG file to open it in AutoCAD.

You can choose to continue your drawing or save it to another secure drive on your computer.

Part 2. Repair corrupted AutoCAD files that fail to work or open

If the recovered files won't open or won't work in the drawing manager, don't worry. You can find wanted solutions in this part.

Method 1. Repair Corrupted or Not Working CAD Files with Drawing Utilities

If you receive the 'Drawing file is not valid' error message while trying to open a CAD file, try below tips and you'll get your problem fixed:

Recover Command allows you to directly restore lost AutoCAD files when you delete or lose them. Here are the detailed steps.

Step 1. Open the corrupted DWG file in AutoCAD and click the AutoCAD icon at Tools column > Drawing Utilities > Recover.

The Recover option will repair a damaged drawing file automatically.

Step 2. When the process finishes, check the repaired CAD file. If it's OK, save it back to your local drive.

Bonus Tips to Back Up and Protect AutoCAD Files

Besides restoring lost or corrupted AutoCAD files, we'd also like to suggest you have a backup plan for protecting your valuable CAD drawings.

Here are two practical tips for you to follow and fully back up AutoCAD files on your own:

# 1. Enable AutoSave in AutoCAD

Step 1.Click the AutoCAD icon at the Tools tab, select "Option".

Step 2.Go to the Open and Save tab on the Options window, check the Automatic save box and set the autosave frequency such as 15 Minutes between saves.

Click "Apply" to confirm.

Step 3.and click "OK" to enable the AutoSave feature in AutoCAD and keep all changes.

After this, you can directly go back to Method 3 in Part 1 to restore lost or unsaved drawings when you closed CAD or lost a DWG file without saving.

# 2. Run File Backup Software to Automatic Backup Saved CAD Files

As for the saved CAD files on your local PC, we also suggest you back up them regularly. You can manually copy them to an external hard drive or directly apply a file backup software with a schedule backup feature to fully protect these CAD files.

Here you can try EaseUS Todo Backup for a simple file backup process. It allows you to create a scheduled backup plan to automatically back up desired CAD files and other valuable data on your PC in only a few simple clicks.

Step 1. For the first time you use EaseUS Todo Backup to back up files, click Create backup on the home screen and then mouse click the big question mark to select backup contents.

Step 2. Since you're going to back up files and folders on your computer, go on with the "File" backup mode, where you can select pictures, videos, documents and all other types of files to back up.

Step 3. Follow the paths to locate the files, folders or directories you want to back up, select them all and click "OK".

Step 4. Now you need to select a backup location to save and retain the backup.

Step 5. EaseUS Todo Backup allows users to save the backup files to every device that is handy for you, like a local hard drive, external USB drive, SD card, network drive, or a NAS drive, plus a cloud drive of the EaseUS brand. We personally recommend users to choose the cloud drive prior to a physical drive to save important backups due to the greater accessibility, flexibility and safety.

To be able to access to EaseUS cloud, all you need is an email registration and login.

Step 6. If you're interested in an automatic and intelligent backup schedule for the next file backup task, go on with the "Options" setting. There you can encrypt a confidential file backup, compress the backup image size, or customize a backup scheme to tell the software in what time to start the next backup.

Customize an advanced and automatic backup task here:

Step 7. Click "Backup Now" to start the file backup process. Your completed backup files are visible on the left area in a card style.
