My AutoCAD drawing file (. dwg) has become damaged :
The file does not open.
The program hangs or crashes in AutoCAD.
Slow program response when working with a file.
Error message when opening or working with the file.
Some commands do not work or are delayed.
Inexplicably large file size.
Problems with Show/Regenerate command.
The disappearance of the previously created elements.
What to do?! I'm shocked ....
