Hi DEV! I built DiskGeek because I was tired of disk-analyzer tools that were either abandoned, bundled with adware, or missing the one feature I actually wanted: near-duplicate detection via perceptual hashing, not just exact-match.

It's a free, self-contained Windows tool (Avalonia UI on .NET 8) that does:

List view + treemap view of what's eating your space

Exact and near-duplicate file detection (perceptual hashing for images)
