: IE and Windows Explorer are integrated in that they listen for each other
: (Try entering c:\ into Firefox and you'll note that Windows Explorer
: automatically open) in that if you make a reference to the file system in
: the location bar in IE, Windows Explorer will open.

If you enter c:\ in Firefox you get a directory listing, obtained from

If you enter c:\ in Internet Explorer you also get a directory listing. The
"shim" changes, because you're now in a different IE security zone. However
the process displaying this listing is *still* iexplorer.exe. It's just that
showdoc.dll or urlmon.dll (or whatever dll is responsible for working out
which sec zone you're in) has determined that your now in the "my computer"
zone rather than say the 'internet' zone. Explorer hasn't "opened" - you're
still using iexplore.exe

As for the "listening" thing - how is this any different to any other app?
Word doesn't "listen" to see if you've double-clicked a Word document.
Instead there is invocation process whereby handlers for certain file
extensions are registered with Windows, and the handler can be invoked when
you attempt to use a certain file. This doesn't mean that "word is integrated
with Explorer" or similar, and so I don't understand what's special about the
explorer/iexplore integration. What *is* common is certain underlying .dlls
that provide functionality like HTML rendered (mshtml.dll) and zone security
(urlmon.dll). These .dlls can be loaded into many processes (eg outlook,
explorer, iexplore) rather than having separate dlls for each applications


: But they're not integrated in the sense that one requires the other.
: Explorer.exe is responsible for more than just file browsing... the icons
: and any interface that isn't shown in a Microsoft Management Console is
: going to use some form of the explorer.exe functions.

Explorer itself doesn't do much. Much of this functionality is implemented in
other dlls which can be loaded by the Explorer process (or loaded by other
processes as well). Explorer itself is only about 1MB in size. IExplorer is
even smaller (about 90kb).
