DISK INSIGHT
Scan first. Decide for yourself what matters.
Disk Insight maps your storage, surfaces the biggest files and folders, groups usage by file type and location, and keeps repeat scans readable. It does not contain a cleanup button and it does not make hidden changes.
Largest files & foldersFind the pressure points instead of guessing.
Storage breakdownsSee what kind of data is consuming space and where it lives.
Repeat-scan historyCompare how storage changes over time.
Exportable resultsSave CSV or JSON without uploading your scan.
THE STONEFERN STANDARD
A utility should earn trust through behavior.
Disk Insight is intentionally narrow: inspect storage clearly, preserve user control, and avoid pretending to “optimize” anything it does not need to touch.
No cleanup button.
The current public release does not delete, move, rename, or automatically clean files.
No mystery claims.
Version, release status, privacy behavior, and legal terms are available before download.
