How to restore broken DWG file?

I tried to restore it AutoCAD, but nothing happened. I am using AutoCAD 2014. The file was created in a similar version of the program. I created it is not very long, but a couple of times a clean computer from unnecessary files including the location of temporary files. And in the end when I need them, I do not have backups. I know that a little too far with cleaning my computer, but I need a drawing which is in this file. Please tell me how to recover it. No special computer problems were not in the last couple months. No viruses, breakdowns system failures. But the file is broken.

Did you try using the RECOVER command?

Is there a .BAK file?

How did the file get "broken"? Did your computer crash or shut off unexpectedly while working on the drawing?

You could try to open a new drawing, isert your broken DWG as a block and, if it works, explode it.

I hope you did not clean here, look here.

Options, Files, there look for a copy of your file with the extension .ac $. There may be empty files and complete, put it simply look there. And when you find, then just change the extension to BAK and whether DWG.

Here's another way to recovery, I will not copy it here if you want yourself to read this: http://www.filerepairforum.com/forum/cad-tools/cad-tools-aa/dwg/561-how-to-recover-autocad-files-from-flesh-card
