Having read through a couple of Google answers on this problem it seems that the basic Windows commands for copying do not allow you to preserve the dates of file creation etc. But there is a programme called Richcopy Click Here that allows you to do so. I've not used it but since you still have the original files with their original dates it should be a simple matter to copy them with Richcopy and then move them to your new machine. I would be interested to hear how you get on.
