Find Oversized Log Files

Quick answer: Large log files may occupy unexpected disk space after errors or long uptime.

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. Scan the relevant application directory.
  2. identify *.log or similar blocks.
  3. determine which app writes them.
  4. rotate or clear using that app's supported controls..

How to verify the result

The growing log source is identified and subsequent file growth can be monitored.

Important limitationDo not erase logs needed for troubleshooting or compliance.

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.
