When you save a drawing file, Autocad creates a file with a .dwg extension.
For example, if you save a drawing as 12b, Autocad saves it as 12b.dwg.
The next time you save that same drawing, Autocad replaces the old with the new and renames the old version 12b.bak. The old version is now a back up file.
(Only 1 backup file for each drawing file is stored.)
How to open a back up file:
You can’t open a “.bak” file.
It must first be renamed with a “.dwg” file extension.
How to view the list of back up files:
The backup files will be saved in the same location as the drawing file.
You must use Windows Explorer to locate the .bak files.
How to rename a back up file:
1. Right click on the file name.
2. Select "Rename”.
3. Change the .bak extension to .dwg and then press <Enter>.
Recovering a Drawing
In the event of a program failure or a power failure any open files should be saved automatically. (Refer to page 2-24.)
When you attempt to re-open the drawing the Drawing Recovery Manager will display a list of all drawing files that were open at the time of a program or system failure. You can preview and open each .dwg or .bak file to choose which one should be saved as the primary file.
