I saved a file with the wrong name (over an another file) and lost the old
files data (yesterday). Is there any way to go back and find the old file
(the data before I saved over it). My o/s -pc has an auto-recovery feature.
If I reboot into yesterdays date, email myself the previous file would I be
able to reboot back into todays date and open the email?

Thanks for any help (as long as the answer isn't that I am screwed).
