See what's on
every drive.
Point Fathom at any volume and get a complete picture of what's there. File counts, media types, storage consumption, duplicates. One view across every drive you own.
Scan
Point at a volume and Fathom walks the entire filesystem. Every file catalogued by type, size, and modification date. Media files get deeper inspection — codec, resolution, duration.
Visualise
Treemap, sunburst, or flat table — see where your storage went. Drill into any folder. Filter by media type, date range, or file size. The big files surface immediately.
Catalogue
Every scan persists. Unplug a drive and Fathom still knows what was on it. Search across all drives at once — find that clip from three shoots ago without mounting anything.
Every drive, every file, one view. Know what you have.
