The short version

  • Each has a real cost: 7-Zip windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided; WinDirStat it walks the directory tree rather than reading the NTFS master file table, so a full scan takes minutes where WizTree takes seconds on the same drive.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

7-Zip

  • Windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided
  • Linux and macOS support primarily through command-line tools; no native file manager integration on these platforms
  • User interface design is dated compared to modern alternatives; visual feedback and UX polish lag behind commercial archivers
  • ARM64 support limited to Windows; no ARM64 build for Linux or macOS despite growing ARM adoption
  • No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

WinDirStat

  • It walks the directory tree rather than reading the NTFS master file table, so a full scan takes minutes where WizTree takes seconds on the same drive.
  • The version most users have installed is the 2007 build, and because it was dormant for so long, search results and download mirrors still point at it.
  • It is Windows only, so a mixed estate needs a different tool for macOS and Linux machines.
  • There is no scheduling, reporting or export for fleet use, so it answers a question on one machine at a time rather than monitoring storage across an organisation.
  • Hard links, junctions and deduplicated volumes can be counted in ways that make the totals disagree with what Windows reports, which causes confusion on servers.

Answered from the vendors’ own pages

7-Zip: Is 7-Zip free to use commercially?

Yes. 7-Zip is licensed under GNU LGPL with BSD 3-clause portions, permitting commercial and personal use without fees, registration, or restrictions.

Source
WinDirStat: Is WinDirStat still maintained?

Yes. It was dormant from around 2007 until new maintainers resumed development and released the 2.x line with multithreaded scanning and current Windows support.

7-Zip: What file formats does 7-Zip support?

7-Zip natively creates 7z archives and supports packing/unpacking ZIP, GZIP, BZIP2, XZ, TAR, and WIM. It can unpack 30+ additional formats including RAR, ISO, DMG, and VirtualBox disk images without requiring external tools.

Source
WinDirStat: Can I use it at work?

Yes. It is GPL licensed with no personal-use restriction, which is the practical advantage over free-for-personal-use alternatives in this category.

7-Zip: Does 7-Zip work on macOS and Linux?

Yes. 7-Zip operates on Windows, Linux, and macOS. Graphical interfaces are optimised for Windows; Linux and macOS primarily use command-line tools. Port and third-party GUI applications extend functionality on these platforms.

Source
WinDirStat: Why is it slower than WizTree?

Different method. WizTree reads the NTFS master file table directly; WinDirStat traverses directories, which is slower but works on any filesystem, including network shares.

WinDirStat: Does it run on macOS or Linux?

No. Separate projects exist with similar treemap interfaces, but WinDirStat itself is Windows only.
