you can add whatever you'd like to the end of the file name, but you have to remember that these are not the original files you were working with (as far as the operating system is concerned). They were created fresh on the day you pasted them and have no information of the previous copy.

you could probably use a hex editor, but it wouldn't actually be "retrieving" previous dates as much as manually inserting them, at that point it would probably be less trouble to just put it in the file names or come up with a new organizational scheme.

Do the files still exist somewhere with the original dates?
Because it's entirely possible to just get a list of filenames and dates from the old system, then update the dates of those same files on the new system.
