TYPO3 Core

I need to unzip files in filelist. But the settings do not work. Everything is set up as mentioned in [[http://docs.typo3.org/typo3cms/FileAbstractionLayerReference/Administrators/Permissions/Index.html]]

UserTS (or GroupTS):
permissions.file.default {
unzipFile = 1
}
permissions.file.storgage.1{
unzipFile = 1
}

Setting the unzip_path in "Installation/All Configuration" (unzip is installed there and has the name unzip)
[BE][unzip_path] = /usr/bin/
