So, below is a demo of how to use the example app in windows, 
where I unzipped a 2GB directory structure from a 1GB zip file, 
tzip.zip.

The example supports several forms of commandline:
uzp zipFilename to unzip in current folder, or
uzp zipFilename destFoldername to unzip into the destination 
folder, or
uzp zipf1 zipf2 zipf3 destFoldername to unzip multiple zip files 
to dest folder, or
uzp zipf* destFoldername to unzip multiple zip files (wildarg 
expansion)to dest folder

It overwrites existing directory entries without asking in the 
current form.
