so, for ziping unziping files you need installed those packages:
zip 2.32-1maemo2 and unzip 6.0-1maemo1. Those can be installed downloading zip and un-zip addon for file manager from extras devel.

tar.gz - the archive is created but when i try to open is empty

tar.bz2 - it's showing me that the archive is created but i can't find it in the place where i created...

please help witth last two!

a suggestion (question): it is possible to include in the deb file all the needed packages for handeling archives. if no then create dependencies of those files.

thanks!
