Even better, wait until people discover 7zip's 'parser mode' on Windows (especially). Right click a file -> 7zip -> Open archive -> #:e mode. Really fun way to quickly carve out files and snoop around. I use it like a poor man's binwalk to extract firmware files and updates and etc out of things to usual success.

(#:e Parser mode, ignoring full archives, and checks every single byte position of a file for 'start of archive' bytes to parse archives out of a larger file.)
