I'm using AutoCAD 2012 LT and have just had a fatal error message. AutoCAD asked me if I want to save a recovery file which I agreed to, obviously. Now that I'm trying to recover the file, titled <FILENAME>-recover.dwg, its telling me that the drawing file is not valid. The BAK files are older than the recovery file, as is the originally saved file. I want to open the most recent, recovery file, but can't... Any ideas?!
It was posited earlier to look in your Temp file for SV$ files and see if these are more recent.
Search SV$ if the Temp folder is not readily apparent.
Have you tried to just use Recover from the big red A menu?
And what size is the file that you are trying to open? It may not be viable.
Temp File location can be found under OPTIONS; Files tab:
Looking at explorer, the recovery file (which I can't open) is 11.6MB whereas the original file was about 6MB. I haven't done much to it between these files to justify that much of a hike...
The recovery manager (through the big red A) won't open it either.
The SV$ file doesn't exist, even though I've got my autosaves and backups switched on.
We have just upgraded to 2012 from 2009, and it worked perfectly well then, I know because the pcs suffered fatal errors quite regularly, which is the reason for the upgrade in the first place - AutoCAD just got upgraded with it.
I have had this happen to me several times. The recovery file generated can’t be opened. I found that at that point there was little that I could do. BAK files are always older than the DWG file they are backing up. Since it seems there is no SV$ I think that all you can do is open the DWG file and redo your work. This happens regardless of the release of software. It's unfortunate. To help remedy situations like this I tend to save (by pressing CTRL+S) every few minutes. It's a habit that I have gotten into and has saved me several times. Also check your auto save settings. Bump up the save time interval. Make it ten or maybe even five minutes. The problem with that though is that it may interrupt your work to execute the save. I find it annoying when it does which is why I manually save the files myself so often.
I know this doesn't help your current situation and I wish I could help there. I wanted to share my experiences with you demonstrating how I deal with this constant issue.
i am unable to open this file please any body can open this file and send it to me as soon as possibe i am very thankful please repair this drawing and send me on this mail firstname.lastname@example.org

There are several methods how to try to open a corrupted AutoCAD drawing file.
Use the Recover command Open the file and press ESC key just before Regeneration/Error message, save to DXF, load, save as DWG, Audit Insert the complaining DWG as a block into an empty drawing
Open/save the DWG in an older version of AutoCAD or AutoCAD LT or Actrix
