Question - How you can open a drawing file that was created with the automatic save features?
Answer -
Autocad files have an extension of “.dwg” and will only open those files having this extension. To open the drawing files you have to rename it, by using Explorer or DOS prompt you can do that. If you are using EXPLORER you have to make sure that the option of “Hide file extensions for known file types” is not enabled. After the file is copied you can rename and use the OPEN command in Autocad to open the drawing.
