Here's the story. I've been working off of a couple Excel files on my USB stick since I don't have a single computer to work on, saving on the USB, not the PC as I went along. Yesterday, the USB broke in two, at the silver part (So the part that actually goes into the computer has broken off). I was wondering if there are any temporary excel files in the PC that I can use to restore the data. Or is it gone forever. I was working on both Windows XP and Windows 7, on Excel 2007 and 2010 respectively.
