|Be careful, the creation date can be a bit misleading. I have MS-DOS files going back to 1991 yet they show a creation date of 2007. The last modified date is 1991 though. I haven't used MS-DOS since 1995.|
The files creation date is the date they were created on the computer they reside on, not necessarily the date the files were first made.
And if you are using Vista, you wont be using MS-DOS, You will be using a command prompt.
