This guide walks you through every reliable method for AutoCAD file recovery after crash, from automatic save locations to manual drawing inspection. You'll also learn exactly what to do when AutoCAD crashed how to recover unsaved changes, plus how to set up preventive safeguards against future failures.
Losing a drawing (DWG file) you have been grinding on for hours because AutoCAD crashed. Are these the drawings gone forever?
As a matter of fact, you can recover files for AutoCAD after a crash in different ways. This guide walks you through every one of them, from the quickest built-in fixes all the way to dedicated recovery tools.
When AutoCAD crashes, the program terminates abruptly before it can execute its normal shutdown sequence. That sequence includes saving temporary files, flushing cached data to disk, and properly closing the DWG file handle. Without that orderly shutdown, your drawing file can end up in a corrupted state — half-written, with broken internal structures that AutoCAD no longer recognizes as a valid DWG.
At the same time, the software typically does manage to dump an emergency backup somewhere. The AutoCAD crash recover drawing mechanism, which AutoCAD calls the Automatic Save feature, kicks in periodically while you work and creates snapshot files with .sv$ extensions. These snapshots are your lifeline, assuming you did not disable the autosave timer somewhere along the way.
By default, AutoCAD stores automatic save files in a temporary folder. The exact path varies depending on your operating system and AutoCAD version, but it usually lives under the user's AppData or Temp directory.
You can find it by opening AutoCAD, typing SAVEFILEPATH at the command line, and noting the folder that pops up.
Inside that folder, you will find files with extensions like .sv$, .bak, and sometimes .dwl or .dwl2. The .bak file is a direct copy of the last manually saved version of your drawing, while the .sv$ files are the automatic snapshots. Knowing these file types is half the battle when you are trying to piece everything back together after a crash.
When it comes to getting those drawing files back, you have three broad categories of tools at your disposal.
AutoCAD ships with its own Drawing Recovery Manager, which is the first thing you should check after a crash.
1. When you relaunch AutoCAD, the Drawing Recovery Manager typically opens on its own — it is a panel that lists any drawing files that were open during the crash alongside any available backup and autosave versions.
2. From here, you can open each version, inspect it, and decide which one has the most recent changes intact.
There is also the Drawing Utilities menu, tucked under the Application Menu, that gives you access to a Repair tool. The Repair option attempts to fix corrupted DWG files by stripping out damaged objects and rebuilding the internal database. Sometimes it works brilliantly; other times it does nothing at all. It really depends on what got corrupted.
For files that will not open normally but are not destroyed, the AutoCAD Recover command is worth a shot.
1. Launch AutoCAD, but don't open any drawing.
2. Type RECOVER in the command line and hit Enter.
3. In the file dialog, browse to your problematic DWG file and select it.
4. AutoCAD will attempt to repair the file and open it.
This is different from simply trying to open the file — the recover command performs a deeper audit of the file structure. When you use the AutoCAD recover command on a drawing that was caught mid-save during a crash, it will often patch up enough of the damage to get you back in business, though you might lose the last few operations you performed.
Here's a trick many users overlook. AutoCAD quietly saves your work at regular intervals—by default, every 10 minutes—into an autosave file with the .sv$ extension. You can locate these files like this:
1. Click Files > Options > Automatic Save File Location in AutoCAD.
2. Once you find the .sv$ file that matches your drawing name, copy it, rename the extension from .sv$ to .dwg.
3. Then try to open it. You might lose only the last 10 minutes of work instead of everything.
Your .bak backup files work similarly. These are created when you save a drawing manually. If you find a .bak file in your drawing folder, copy it and change the extension to .dwg.
Sometimes the built-in tools just don't cut it. Maybe the file is too badly corrupted, or you've accidentally deleted the original, and the autosave files are nowhere to be found. That's where data recovery software comes in, and MyRecover is a solid option for this exact scenario.
Here is how to recover AutoCAD files after crash with MyRecover on a Windows 11/10/8/7 computer:
1. Download MyRecover and install it. Do not install it on the drive that you are recovering files from in case of overwriting.
2. Open MyRecover, click Disk Data Recovery, choose the drive where your AutoCAD files are located, and hit Scan.
3. Once scanned, preview and select the AutoCAD files you need, and hit Recover.
4. Select a safe location to keep them safe.
What is the first thing I should do when AutoCAD crashes?
A: Restart AutoCAD and look for the Drawing Recovery Manager—it usually appears automatically. Select your affected file and follow the prompts to restore the latest autosaved version. If it doesn't show, go to Options > Files tab, find your autosave folder path, and look for .sv$ files—those are your backups.
Can I recover an unsaved AutoCAD file without any backup?
A: Yes, if autosave was on (it's on by default). Navigate to your autosave folder (Options > Files > Automatic Save File Location), find the .sv$ file matching your drawing name, copy it, rename it to .dwg, and open it. You'll recover most of your recent work.
What's the difference between the RECOVER and AUDIT commands?
A: RECOVER repairs a corrupted DWG file before opening it—ideal when you can't open the file at all. AUDIT runs on an already-open drawing to check and fix errors within that session. Use RECOVER first, then AUDIT and PURGE afterward for a thorough cleanup.
Is it safe to use third-party recovery software like MyRecover for AutoCAD files?
A: Yes, with reputable software. Stop using the affected drive to avoid overwriting data, and always save recovered files to a different drive. MyRecover reads data without altering your original drive, but download it only from the official source.
Why does my recovered file still show errors after using RECOVER?
A: RECOVER may not catch every corruption issue. Run PURGE to remove unused objects, then AUDIT with the "fix errors" option. If problems remain, use WBLOCK to export clean geometry to a new DWG, then run RECOVER on that fresh file.
How can I prevent AutoCAD file corruption in the future?
A: Shorten your autosave interval to 3–5 minutes. Run AUDIT and PURGE regularly on active files. Store files on a reliable local drive rather than a network location, and keep a separate backup system—cloud sync or external drive—for extra safety.
