I have a question on regards to this PasZip unit:

In the function above the supplied files wind up in the zip archive as
intended, but I would like to improve it just a little bit by also
setting the extract dir to the name of the zipfile.
So if the zip is named PP1.zip I want the contents to be extracted to
subdir PP1 in the dir where the zip is located.

Is there anyone here who has used PasZip.pas from Synopse and have a
solution?
