Is it possible to create an archive in whatever format containing files with identical name located in the same folder? If yes, how?

I need this for some testing purposes. The target OS is Windows. Thank you.

At least tar and cpio should be able to handle that. GNU tar won't care if you add a file twice, for example:

tar cf foo.tar bar baz bar

That should create a tar archive containing the file 'bar' twice.

If a file is appended to a tar archive, at least with GNU tar, that already exists then tar does some weirdness which boils down to when you extract/delete, only the last appended copy is extracted / deleted.
