Unclear how to batch compress items as separate 7z files. Also not clear how to automatically save compressed files next to the originals in the same folder, or how to automatically move original items to the trash automatically after compressing. I have heard some reviewers compare this app to Winzip, but I can't find any settings or preference options that offer anything even remotely resembling Winzip.
