Ok, so I got a phone call from grandma. So the details on what actually happened may be a bit fuzzy. But basically she is writing a very long document, and she has been saving it at about every paragraph, however she hasn't been making back up copies of the file! Anyhow, now when she opens the document, its blank. It seems that maybe she accidentally deleted all the text and then saved it.

does anyone know if I can backtrack 3-5 days to get the file back?

please let me know!
