Filter by File Extension

Quick answer: Use SpaceSniffer filters such as `*.jpg` to focus the treemap on matching file types.

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. Complete a scan.
  2. enter `*.jpg` in the filter box.
  3. press Enter.
  4. inspect visible rectangles.
  5. clear the filter to restore all files..

How to verify the result

JPEG matches are emphasized in the visualization.

Important limitationFiltering hides unrelated entries visually; it does not delete them.

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.
