Introduction

In the realm of file compression and archiving on Windows, 7-Zip has long been a staple due to its efficiency and open-source nature. However, as Windows evolves, so do user expectations for software that integrates seamlessly with modern system aesthetics and functionalities. Enter NanaZip, a contemporary fork of 7-Zip designed to align with the latest Windows experience.

Background: The Evolution from 7-Zip to NanaZip

7-Zip, developed by Igor Pavlov, has been a reliable tool for file compression since its initial release in 1999. Its open-source model and high compression ratios have made it a favorite among users. Despite its strengths, 7-Zip's interface and integration have remained relatively unchanged, leading to a gap between the software and the modern Windows environment.

Recognizing this, the M2Team developed NanaZip, aiming to modernize the 7-Zip experience. The name "Nana" translates to "seven" in Japanese, paying homage to its predecessor while signaling a new direction.

Key Features of NanaZip

Modern User Interface

NanaZip introduces a refreshed UI that aligns with Windows 10 and 11 design principles. Notable enhancements include:

  • Dark Mode Support: Users can switch to a dark theme, reducing eye strain and matching system-wide settings.
  • Mica Material Integration: On Windows 11, NanaZip utilizes the Mica material, providing a translucent, blurred background that adapts to the desktop wallpaper, enhancing visual appeal.

Enhanced Windows Integration

NanaZip offers deeper integration with Windows File Explorer:

  • Context Menu Support: Users can access NanaZip's functionalities directly from the right-click context menu, streamlining tasks like file extraction and compression.
  • MSIX Packaging: Distributed as an MSIX package, NanaZip ensures a modern installation experience with benefits like cleaner installations and easier updates.

Advanced Compression and Format Support

Building upon 7-Zip's capabilities, NanaZip supports additional compression algorithms and formats:

  • Additional Codecs: Support for Brotli, Fast-LZMA2, LZ4, LZ5, and Zstandard codecs enhances compression efficiency.
  • Extended Format Compatibility: NanaZip can handle a broader range of archive formats, including NSIS, UFS/UFS2 file system images, and more.
