I'm guessing that whoever wrote arc-mode tried to avoid external tools as much as they could, since some of the wide-spread tools are not free software, and the free ones might not be installed. Also, IIRC arc-mode allows you to edit the file's attributes in ways that might be impossible with external tools. Anyway, if someone wants to rewrite those parts of arc-mode to use external tools, or perhaps fall back on that if the file's size is too large for Emacs, I'm sure that would be a welcome addition. > Contrary to tar-mode, for example. tar-mode _could_ do the same (i.e. use the external `tar' program).
