AutoCAD file recovery: check backups before disk recovery
How can I recover a missing AutoCAD or CAD file?
Short answer
First check AutoCAD's own safety nets, not the disk: the Drawing Recovery Manager, automatic save files with the .sv$ extension and the .bak copy next to the DWG. Renaming a .bak file to .dwg restores the previous save. Only when no such copy or backup exists is a general disk scan worth trying.
The situation
A DWG or CAD project is missing, damaged or closed before it was saved.
A DWG or CAD project is missing, damaged or closed before it was saved. If the original source has not been written to again, useful file-system traces or data blocks may still remain for CAD project drive. A read-only scan can assess the source, but no result should be promised before that examination.
01 / Diagnose
Work out what actually disappeared
AutoCAD recovery files, automatic saves and backup copies often provide a better first route than raw disk scanning. For CAD project drive, first separate a missing path, folder or volume name from actual deletion. That distinction determines the safest next recovery step.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Disconnect or remove CAD project drive and prevent further writes.
- 2
Write down the device, the date and the last action before the loss so you can match recovered files later.
- 3
Check known destinations, backups and trash without restoring anything onto the source.
- 4
Export every candidate only to internal storage or a physically different drive.
Check application recovery folders and backups first. File Recovery Hero focuses on media files and is not a DWG repair tool. Do not record a test file and do not approve formatting or file-system repair.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
Software cannot reconstruct overwritten blocks or storage cells that are no longer readable. If the source disconnects repeatedly or becomes unusually warm, a professional laboratory is the safer route.
04 / Verify
Check the recovered content, not just its name
Validate files recovered from CAD project drive completely: compare the size and format, then read the content from beginning to end. A preview or surviving filename is not proof of a complete recovery.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can CAD project drive be recovered in this situation?+
A DWG or CAD project is missing, damaged or closed before it was saved. If the original source has not been written to again, useful file-system traces or data blocks may still remain for CAD project drive. A read-only scan can assess the source, but no result should be promised before that examination. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Check application recovery folders and backups first.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
Validate files recovered from CAD project drive completely: compare the size and format, then read the content from beginning to end.
