SpaceSniffer vs TreeSize

Quick answer: SpaceSniffer centers the treemap, while TreeSize offers a directory-oriented reporting approach.

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

  1. Choose the same scan scope.
  2. compare folder hierarchy, filters, permissions, and export.
  3. select according to task needs..

How to verify the result

The preferred interface makes it easy to locate specific large folders.

Important limitationDo not imply all features or licensing terms are identical between products.

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.
