EtreZip does not require your administrator password to install. EtreZip does not require kernel extensions that can crash or destabilize your machine. EtreZip keeps .DS_Store files and __MACOSX folders out of ZIP files (unless you want them there). EtreZip’s ZIP files are fully compatible with the the native ZIP software in OS X. EtreZip supports Finder ZIP files larger than 4 GB and the new ZIP 64 standard. EtreZip opens not just ZIP files. It also opens any document type like EPUB or DOCX that is actually a ZIP in disguise. EtreZip includes a QuickLook plug-in to display the contents of any ZIP file by pressing the space bar in the Finder or any application’s file open dialog.
