SpaceSnifferVerify a SpaceSniffer ZIP Download
Use this workflow on an authorized Windows 10 or Windows 11 computer. SpaceSniffer shows a size-proportional view of storage; always inspect the source file in Windows before changing or deleting it.
Step-by-step workflow
- Check the developer's download page for the SHA1 value.
- download the ZIP and retain it unchanged.
- run Get-FileHash on the ZIP in PowerShell.
- compare the entire hash string against the published value..
How to verify the result
The calculated hash matches the developer's published value for the same release archive.
Why this matters
SpaceSniffer is a visualization tool, not a diagnosis of file necessity. The important outcome is an identifiable path and measurable file size, checked against the same Windows volume and with permission to inspect it. If the scan is incomplete, report that limitation instead of treating missing paths as zero bytes.
More targeted troubleshooting
If the result differs from what File Explorer reports, clear the filter field, allow scanning to finish and check the permissions of the specific directory. Repeat on a smaller known folder when you need to isolate a scanning limitation. Always distinguish a changed treemap view from an actual change in free space.
