Hi
if you don't have a backup copy probably no chance. You may try a file
recovery tool (search Google for some free ones) to recover your deleted
file
1. Yes, if you previously made a backup copy with a different name or
storage location.
2. Possibly, if you had saved the file at least once in Excel. A
third-party restore program may be able to find your missing file.
3. No, if you had been working on a new spreadsheet and had never saved
it at all.
