Those aren't the files you need, first off do you have autosave setup or you are out of luck. If you crashed then the file recovery manager should have started automatically, you did save the file at some point I hope, if you where working on a new drawing from a template then again you will have problems. Anyway 2 things to try open the DRAWINGRECOVERY manager using that command, and see if your file is listed there, or look in C: Users YourName AppData Local Temp DRAWING.sv$ this is the map where you should find any bakups, again look for your filename with the extension.sv$ the date and time will help you locate it. If its there copy the file to somewhere else and just change the.sv$ to.dwg.
A file with an extension of.DWL is known as a AutoCAD DraWing Lock File. These.DWL files can be opened on Windows and Apple using programs. Useing Auto Cadd 2008, going through some drawings and seeing.dwl and.dwl2 files. What are they? And do I need them? Can I delete them?
For your further info, they are always there for each drawing you have open (though they might not be visible as they are system files), it can be handy on a network when you are told the drawing is already open by another user, to see who has a drawing in use, by double clicking on a.dwl it should open in notepad and give you the name of the user and/or the computer name. When you close a drawing normally they close down, if you have any of these after a crash they can be safely deleted (windows won't allow you to delete them if they are in use, so you cannot delete one by mistake).
The.dwl2 is also a text file, and I have to be honest I have no idea what exactly they do, or why there are 2 of them. Hi Steven, got a problem with my CAD file drawing most likely as what stated above.dwl & dwl2 these are the 2 documents left on the location where i save my files since i open it. What i did is i restart the system without closing the cad file what i work for then a pop up msg came to save my Cad file, is selected save and close. When the system is open i can't able to fine my CAD file and the other thing is the autosave backup files on my CAD settings was set on disabled. I spend my entire time and effort on that darwing and now in just a blink of seconds its gone.
