--- Comment #15 from Bernhard Kölbl besentv@gmail.com --- I wrote a little test case for this, which seems to do the same thing as Anastasius' script.
The reason why zips can't be viewed as folders is because it doesn't seem to be implemented. My test case ultimately calls SHELL32_BindToChild, that rejects binding to files, which in case of a zip file seems to be wrong behavior?
