The short version

  • Each has a real cost: LibreOffice real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question; 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.
  • They diverge on capability: LibreOffice covers Full suite, WinDirStat covers Treemap visualisation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

LibreOffice

  • Real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question
  • Mobile support is weak, which is disqualifying for a workforce that reviews documents on phones
  • Complex Microsoft Office documents still lose formatting in transit, so exchange-heavy workflows need testing with real files
  • Central policy management, conditional access and audit tooling are thin against the commercial suites
  • Advanced spreadsheet work is where the gap with Excel is widest, and it affects exactly the users least willing to change

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

LibreOffice: Is LibreOffice really free for business use?

Yes. It is open source with no per-seat licence and no restriction on commercial use. The Document Foundation is funded by donations and sponsors.

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.

LibreOffice: Does it have AI features?

No. The 26.8 release states it contains no generative AI, that documents are not transmitted to remote services, and that no component requires network access.

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.

LibreOffice: Can it open Microsoft Office files?

Yes, and save back to them. Round-tripping complex documents is imperfect between any two suites, so test with your own files before committing to an exchange-heavy workflow.

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.

LibreOffice: Why do governments use it?

Two reasons: no per-seat cost at scale, and OpenDocument is an ISO standard implemented by more than one vendor, which matters for archives that must stay readable after a vendor relationship ends.

WinDirStat: Does it run on macOS or Linux?

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

LibreOffice: What is the biggest reason not to use it?

Collaborative editing. If several people work on the same document simultaneously, Microsoft 365 and Google Workspace are substantially better and that gap is not closing.
