Hi
Can someone recommend me tool for repairing corrupted DWG file?
I have this DWG file that i have used last night, saved it on USB stick, and today when i try to open it,, It says "Drawing file not valid"

Any suggestions?

Tried already, didn't get anything :/

sadness is all around me...

Try to find the *.bak file and change it to *.dwg file.
Sometimes autocad makes auto-save to temporary folder with the extension *.sv$ witch you can also change to *.dwg

Have a look at this discussion forums from autodesk

There is also method to try open it with acme cad convertor. Sometimes it can open file that cad shows as invalid file. Or use last *,sv$, and rename it to *.dwg.
