Disk Space Analyzer notes describe how to install WinDirStat on Windows. The publisher is the Disk Space Analyzer editorial team, an Organization. A mailbox, when a form is present, is for errors in those notes and for questions about those notes. It is a notes mailbox, and it is not a WinDirStat helpdesk, and it is not a mailbox for a named individual. Who publishes: about.

Fallback when email is empty

There is no public email address on this domain. Report a factual error by writing down four facts: the URL that is wrong, the sentence as it stands today, the official source that disagrees, and the sentence that source supports. Put those four facts in the report form when a form is present. If no form is present, keep the four facts until a form ships. Skip attachments. A dump of local scan CSVs is not required to fix a sentence about winget.

How to report an error

If a command, filename, install path, or claim disagrees with the README, winget-pkgs, or GitHub Releases, send a correction with four facts:

  1. The URL of the Disk Space Analyzer note that is wrong.
  2. The sentence as it stands today.
  3. The official source that disagrees: the README, a GitHub release asset list, microsoft/winget-pkgs yaml for WinDirStat.WinDirStat, windirstat.net, or a vendor page such as diskanalyzer.com.
  4. The sentence that source supports.

Usual drift: the winget id WinDirStat.WinDirStat, the full command with -e --id, the default file WinDirStat-x64.msi, the ARM64 and x86 MSI names, portable zip and 7z, WiX machine scope, %ProgramFiles%\WinDirStat, or CSV and duplicate export the README actually lists. How sources are chosen: editorial policy.

Paste the winget command only as a check against the note, not as a new package:

winget install -e --id WinDirStat.WinDirStat

Product bugs

Crashes, scan misses, treemap faults, and delete problems belong on github.com/windirstat/windirstat/issues. That tracker is the project's. The editorial team can fix a wrong filename in a note. Patching WinDirStat itself stays on that tracker. Include the current release tag from GitHub, the Windows version, and whether you used winget or the x64 MSI. A feature is claimed only when the README lists it. There is no personal GitHub account for these notes.

Fetch stays on GitHub Releases or winget. The Microsoft Store listing 9ph1gl95p3wf, Chocolatey, and Scoop are supporting paths the README already names. A wrapper site that promises a verified exe on some other domain is still a wrapper. Walkthrough: download safely.

Questions about install notes

Questions the notes can answer: which file on the current release, winget versus the x64 MSI, MSI versus portable zip, where App Installer comes from, whether to take ARM64 or x64, and how a folder scan differs from a whole-drive scan. Start with home, GitHub, releases, how to install winget, versus WizTree, and guides.

Checking drive use without a treemap sits on check storage on a PC. A short definition sits on disk analyzer.
