So I had a pretty important document on LibreOffice Writer, but now when I try to open it it's just 3 pages of "#".
I've also tried opening it in the Notepad, in which it is pretty much blank. Has anyone seen something like this before, and is it possible to retrieve the text?
EDIT: I'm also not sure if this should be flaired as "Data recovery" or "Software", please tell me if I made a mistake.
