  • Well designed interface


  • No repair tools

Zipware it looks as good as any other premium file compression software and is wonderfully simple to use. Just choose “New” or “Open”, choose the source file or archive, change some optional settings and that's it.

With iOS 11, Apple mobile devices (iPhone and iPad) already have a pre-installed file manager, called Fillet, which allows you to preview ZIP files in internal storage and iCloud Drive.
