Drawing file is not valid...

I don't know what happened, but my autocad file doesn't open up with a message "drawing file is not valid". I opened it at home once in Autocad 2012 - Student version and I open it at school usually every other day in Autocad 2012 - Educational version and it opens up properly at both places. But this tuesday I tried to open it, and it didn't open. Please tell me what the problem. I really need this file to be recovered because this drawing was complicated and I finished it. So, it will be a real pain to do it all over again plus the time I will waste. I am going to attach that file here. If anyone can open it then please let me know and send it to me by saving it again or something like that.

 

Thanks.

Invalid when I try to open it. I tried renaming but still won't open.

Is there a BAK file at any of the locations you mention you can recover and rename? A partial file recovery is better than none. Or even an SV$ Autosave file.

 

At 126k, is there much in this file? That's too small to contain anything other than a couple of lines. Your file got trashed a long time ago, this one cannot have hardly anything in it you cannot recreate in a few minutes if that is the actual file size.

I tried to change the extension of the bak file to dwg and then tried to open, but the same message displayed. Well, it might probably take few minutes or so for experts to draw, but for me as a begineer it takes hours. Please let me know if you have any solid solution to this.

As I noted, going by file size alone a 126k file cannot contain too much. It may have taken you hours to draw a bldg floor plan I have no doubt but you are looking at a much larger file size.

 

Either way, the file you posted is dead and unrecoverable, sorry.

 

Where is your backup? You always need to carry a second reserve backup copy. Thumbdrives are dirt cheap, get a bunch and label/use them all the time.

I think you may be overstating the relationship between files size and the amount of work involved.  You can easily fit an entire floor plan in less than 126KB if the drawing is "clean".  ie no parametrics, dynamics, annotative objects, AEC, regeapps, etc.

 

OP,  You may try starting the Drawing Recovery Manager (DRAWINGRECOVERY)  just to check if it can find a recoverable version

That may be true, only the OP can tell.

Looks like your work is gone.

Just out of curiosity - how are you transferring from one machine to another?

USB drive?

Did you stop or eject the drive before removing?
