Announcing a catastrophe: vital document failed to save, and the message " I/O error trying to read or write to disk [-36] " was displayed. Then when I tried to open the file the message " Bad file format.  " was displayed.
I assume that this was caused by some kind of problem in memory while working with the file, but is there any way that I can recover this corrupted file ?
The document took days to prepare and I can't face the prospect of starting from scratch!
pls help !
