How to find if the document is in more than one folder on my computer?
You would use the search feature on the computer. Right click on
the Start button and choose Search. Put the file name, with its
extension (ie. doc, xls), into the file name field. Scroll down to
the search "in" field and select Drive C. (there is a down arrow)
Then, click search. Some or all may be different versions of the
same file. In the list, you should be able to rename them by right
clicking and inserting "a", "b" and so on to the different
versions. That way, you'll know which one you are in.
