Thank you Google Desktop Search!
Have you ever opened a Word file that you were using as a template, entered new text, and then saved it -- overwriting the original version that you dearly wanted to keep? I did that today with an article about a presentation on which I had taken an hour of notes. After I saved over it, there was no way in Word to retrieve the prior version. I was distraught.
So I opened a browser, used the Google Desktop Search to find the document, and noticed that 12
versions of the article were cached (click on the screen shot to see it bigger). I clicked on "cached" and clicked among the choices until I found the last version of the earlier article before I overwrote it.
I highlighted and copied the article into Word and saved it under a new name. Whew! I just love technology that saves me from my own mistakes.
