Windows Explorer: Create/Modified Date

I need to prepare multiple files to burn and transmit to third party during

asset sale. I'd like to temporarily keep a copy in my current Explorer file

folders. It is important to the other party that a sense of chronological

order be retained. If I copy files over to the new party's folder, then a new

Date Created shows in Explorer. I guess I can get around that by moving the

original to the new folder, then creating a copy for me. However, then I lose

chronological create-date settings in my copies.

The real problem: some .xls files are mixed and must be split apart to

provide the third party only selected data. Any way I go, once I edit the

file, resave, and make copies, all the historical file properties will be

gone. Other than making notes in the "Custom" or "Summary" tabs under File

Properties, is there any way to retain either the Date Created or Date

Modified properties that display in Windows Explorer?
