NanaZIP 6 is out in preview with a lot of UI improvements and new features

While Windows 11's File Explorer is pretty good at handling various archives these days, thanks to more format support, dedicated apps like WinRAR or 7-Zip are still much better in terms of features and performance. NanaZIP, a popular fork of 7-Zip, is a great app for working with compressed files, and with the latest preview update, it became even better.

NanaZIP 6 Preview is now available for download, and with it, developers implemented more XAML-based UI parts. In other words, the app now features more native Windows 11 elements. The latest additions include a reworked address bar, status bar, properties and information dialogs, and a new progress dialog.

Other noticeable changes in NanaZIP 6 include a new "Extract-on-open" feature, which automatically extracts the compressed file when you open it (standard behavior in operating systems like macOS and iPadOS). If you do not like this behavior, you can skip extract-on-open by holding the Shift key when opening an archive. Alternatively, NanaZIP lets you disable the new feature for good in settings.

Also, NanaZIP 6 now has file associations for CBR, CBZ, and ASAR formats, faster performance on startup, the Zstandard decoder instead of 7-Zip mainline's implementation (this improves reliability and reduces potential vulnerabilities), plenty of various fixes, improved localizations, and some changes to the system requirements. The latter now mandates 64-bit versions of Windows 10 2004 (build 19041 and newer) or Windows Server 2022 (build 20348 or newer). The latest update removed all the 32-bit components from the app.

You can find the rest of the changelog for NanaZIP 6.0 Preview on GitHub. If you are curious to give the app a try, get it from the Microsoft Store or GitHub. The stable NanaZIP release is available in the Microsoft Store via this link.
