The problem
Disk analyzers show sizes but not what a file is, which app owns it, or whether it is safe to remove
STRATA
A native Windows disk-space app that reads the NTFS Master File Table directly to show what is using your disk, who put it there, and whether it is safe to delete.

The build
Built a Rust engine that parses the MFT in an elevated helper over a secured named pipe, classifies every file with rule packs, and streams layouts to a WebGL2 UI
The outcome
On the same drive a full scan takes 26.2 s against WizTree's 86 s, and search returns first results in about a millisecond across 5 million file names.
5 features. 7 tools.
- Raw MFT scanning with live USN change-journal updates
- 240 rules across 14 categories and 72 apps, each with a safety tier
- Safe cleanup with a never-delete list, Recycle Bin and one-click restore
- Everything-style search, snapshots, diffs and a duplicate finder
- Treemap, sunburst, icicle, circle-packing and mind-map views in WebGL2
