My guess: I had a project opened on mono/xamarim studio where all 
the files has already been saved before I hibernate the computer. 
The computer somehow lost the power xamarim/mono tried to save it 
but computer aborted before making these files into 
zero-byte-file. A zero-byte-file does happen when a program is 
writing to a file but is prematurely aborted because this write 
isn't transfered to file at same time but to a "cache" instead of 
and at later time written in the file. The computerd turned off 
before it. I think the @Etienne Cimon's method didn't worked well 
because I used the computer after it. Maybe if I had kept the 
computer untouched I could get back them.
