V5 on Win XP laptop.
All work, layers, images, nothing recognisable except for a file pasted in from the forum, is all that remains after I elected to go file save, close rhino, shutdown laptop for evening meal, that went fine, then started it up again afterwards, got the ‘Rhino didnt save properly and saved your project but now do a save on it’ message, amazed to see that, as it closed down apparently perfectly ok, so I then saved the file it offered up, then I open that and everything I had created has gone, layers pics, 2 days hard graft, in fact I think phew, its on about a different file at first, as its so unrecognisable regards content.
File I closed would be 15 feb dated, that which rhino saved was 16 feb dated, and has 2 user created layers, assoc with an object I pasted into it. many hours work vanished. all my layers and design gone.
I select the bak file, remove bak, rename it, try that, still same , all is gone.
I have never had another program do this to me, but Rhino occasionally does so, scary on important work, I hadnt got as far as considering a backup save, not far enough into it to think of such, but all is lost.
This on a win XP laptop, previous failed save might have been same PC.
Is there anything I could dig deep for , any file remnant that might resurrect this.
File was not complex, just maybe 20 dims and a few objects but was the result of much work these last few hours to establish theoretical size from measuring an actual item with vernier to get to that shape.
