Recovery zeroed file

I was writing code when suddely my house's power was cut. Then when I turned on my notebook again, the file I was writing code in is all zeroed. I found a file called myFile.cpp.autosave that also is zeroed. Is there any way I recovery that file? I have a backup (done manually) made about 2 days ago. I wrote fairly amount of code today (the file length difference (the zeroed file size remains the same, its contents that is zeroed) is among 6kb).
Help me guys

Windows might have a snapshot of your file. But the problem is out of scope of this forum really.
