How to read invalid .dwg file?

Question

Data recovery

Hello. Interested in repairing a damaged .dwg file, or opening it for data extraction. The AutoCAD drawing is very old, most likely it has been worn out.

Answer 1

1. Open the window with the settings through the AutoCAD menu and the PARAMETERS button, or use the command line to write H + enter, or RMB in the model space, then PARAMETERS.
2.The PARAMETERS window opens. Select the Open/Save tab. In this window, we are looking for Autosave, set the interval. Or disable the option altogether.
3. In order to find out where the autosave files are stored, go to the Files tab, see the Folder for the autosave file.
The main way to save a drawing is the keyboard shortcut ctrl + s or through the Save icon.
4. To save the AutoCAD file in another version, go to the menu, select Save as, tab Other formats.
5. From the drop-down window, select the folder and version of AutoCad in which we want to save the drawing, click save.
6. I will also offer a more radical way to watch
Autosave - this is more of a backup copy of the file. Not infrequently, AutoCAD gives an error and closes without saving the changes in the drawing. In this case, you will need an autosave backup. Although there is another way to restore a file closed due to problems. Many people use older versions of AutoCAD, in which it is impossible to open a file created in a newer version of the program. For this case, choose the method through save as.
