Sort photos into folders, one keystroke per image.
A thousand-image folder, sorted in ten minutes.
Image Sorter shows photos full-screen, one at a time. You assign keys (1, 2, 3, ...) to target folders. Press a key — the current photo moves to that folder, the next photo appears. A thousand-image triage that would take an afternoon in Explorer takes ten minutes here.
Point at a source folder. Define up to 10 target folders, each bound to a key. The tool displays photos one at a time, full-screen, in source-folder order. For each photo, press the key for the category that fits. The image is moved (not copied), the next one appears.
