Usherr matches your folders to the right titles; nothing is moved, renamed or downloaded again.
Point Usherr at a folder of films or shows. It reads the names, matches each to the right title, and lets you check before anything is added. Your files stay exactly where they are.
Pick Movies or TV shows, check the folder, and press Scan folder.
Confident matches are ticked. Check match rows are worth a look: pick the right film from the list, or Search… by hand. Then Import: every title is in the Library at once, its poster and details arriving a moment later.
Run it again any time: what’s already there is skipped.
