I have a file in an archive that I wish to edit. I can open the archive with 7-Zip without any issues, and copy/modify/paste files into/from the archive (from within 7-Zip). The files have the following properties:

Modified: someDate
Attributes: -rwxrwxr-x
Host OS: Unix

There are more, but you get my point. I'm on a Windows system and as such can't make/edit the files without changing host OS and attributes (and the date of course).

Ideally I'd like a method to copy the properties of one file, and directly paste the over the properties of another file within the archive. So far I've tried a few freeware applications on the Internet (e.g., I've tried Attribute Change, but it doesn't allow you to change much more than the date as far as I can tell).
