drawing file?

Recover a drawing file when the Recover command fails
can anybody tell me how to recover a drawing file if Recover command couldn't make it?
When i use the recover command i get an Autocad message : "Unable to recover drawing file"

Did you try to Recover or Audit the drawing?
Insert into a new .dwg or XREF?
See if there is a .bak file of the drawing and rename?

Now, after I read what you told me, I changed the extension from .bak to .dwg and it worked in one out of four files so it is a good start.
