I believe that Windows normally preserves the creation time on a copy. If not, extracting a tarball with the --preserve should do it.
Gordon,
Thanks for your suggestion.
I'm really a novice. How would I go about extracting a tarball from a Windows machine?
When Windows copies a folder onto the same machine (e.g., to a second drive) it does retain the date-time information. But when it copies to another machine (e.g., a SME file server) it seems to create a *new* folder of the same name on the target machine before copying the folder's contents.
Thanks for your help.
