zip folders support

[avsha...@gmail.com]

Does anyone tried to use zip folders support on wine? Is is possible?
I tried to copy zipfldr.dll and register it, but it does not work.
Since I am a developer I would try to do it. Could you please suggest
a point to start? As far as I know the interfaces of zipfldr.dll are
not documented, so it will not be simple task.

Thanks in advance,
Alexander

What exactly is a zipfolder? Is it the ability to use a zipfile as if it
was a directory? If yes, at what level and how is this support
implemented in windows?

Which wine version? Self compiled or prepackaged?

zip filder support is encapsulated within zipfldr.dll which is
standard COM-component (i.e. exposes DllRegisterServer/
DllCanUnloadNow).
For example in WinXP zip folders support may be switched off by
unregistering zipfldr.dll via regsvr32.
Therefore I may suspect that this support is given on the user (shell
only) level, because CreateFile can't be applied to the files within
zip folder (I am not too sure on this - may be there is some kind of
API hooking+undocumented facilities are used?).
The exposed interfaces of the mentioned library are unknown (to me,
maybe MS published it in any hidden MSDN subsection).

Yes. Please see an answer above.

I think it might be possible to do something like this. However, I don't
know if the needed function hooks are even implemented in wine. You can
ask the devs on wine-...@winehq.org.

Thank you for your answer. I've just sent an e-mail to the developers,
after getting the answer I'll place it here.
