The short version

  • Each has a real cost: AutoHotkey version 2 is a different language rather than a new release, so v1 scripts must be rewritten and the conversion script handles only routine cases, leaving years of accumulated internal automation stranded.; 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: AutoHotkey covers Hotkeys and hotstrings, 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.

AutoHotkey

  • Version 2 is a different language rather than a new release, so v1 scripts must be rewritten and the conversion script handles only routine cases, leaving years of accumulated internal automation stranded.
  • Version 1.1 receives no active development, so teams that decline the rewrite are running an interpreter that will not get fixes for future Windows changes.
  • Antivirus and EDR products frequently quarantine the interpreter and compiled scripts because the same capabilities are used by keyloggers, which turns deployment into a security exception request.
  • Automation depends on window titles, control classes and screen positions, so a vendor application update can break every script overnight with no compile-time warning.
  • It is Windows only with no path to macOS or Linux, so any process automated with it cannot follow the organisation if it moves platforms.

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

AutoHotkey: Should a new project start on v1 or v2?

Version 2. Version 1.1 is not actively developed and every new script written against it adds to a future rewrite.

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.

AutoHotkey: Will compiled scripts trigger antivirus?

Often yes. Compiled AutoHotkey executables are a known malware pattern and usually need to be allowlisted by hash or signed with your own certificate.

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.

AutoHotkey: Can it automate a web application?

It can drive a browser as a user would, but it has no page object model, so a CSS change breaks it. Use a browser automation framework where one is available.

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.
