How can I open an AutoCAD backup file?

Because an internal error, I lost an AutoCAD drawing, however, I have a
backup file, but I cann't open it. I have tried everything that I know
wihtout results.
Somebody can help me?
Thanks.

If you have set Acad to save automatically every few minutes, you will
find the latest saved file with an extension such as *.sv$. It might be
called auto1.sv$, auto2.sv$ and so on. Those files are frequently found in
the windows/temp directory.

Change the .sv$ to .dwg and you should be able to open it. That file will
be the last one saved automatically and, if you set Acad to save every 5
minutes, then you have lost only 5 minutes work time.

 

Close.

How do you do this in Win XP:
"...Set up a directory on your server with WRITE rights, but without DELETE
rights..."

Yes, but I have R14, so cannot comment specifically on versions above
that!

The important bit is the extension .sv$. Search for that and they can be
found
