Know what uses space
Scan accessible folders and drives, then explore their actual on-disk size without losing the small items.
Diskloom
macOS + Windows + Linux
Visual disk space explorer
See what is using your disk space.
Diskloom scans accessible folders and drives, maps their actual on-disk size, finds duplicate files, and includes a practical disk benchmark. Built for people who want to reclaim storage without uploading filenames, paths, or scan results.
- Visual folder and drive maps
- Private duplicate-file comparison
- Built-in disk benchmarking
Everything in one place
Storage cleanup starts with an honest map.
A single storage total does not explain which folders grew, which files are duplicated, or what is safe to review.

Find duplicate files
See which matching files consume storage, compare them privately, and choose the copy worth keeping.
Benchmark when you need it
Measure sequential and random read and write performance with adjustable workloads, throughput, IOPS, and variability.
