How do I open the Duplicates window?
Short answer: Open the menu bar popover and choose More menu ••• → Duplicates, click the Duplicates card on Home, or ask Tuhi to "find duplicate files". The window opens to your last results; a source never checked shows "Not scanned yet." with a Scan now button.
Open the Storage Studio menu bar popover, click the More menu ••• → Duplicates. You can also click the Duplicates card on Home, or ask Tuhi to "find duplicate files" and it will open the window for you.
The window opens straight to your last results, because results are remembered between launches. If a source has never been checked, it says Not scanned yet. — click Scan now to start.
The Home card's subtitle also gives you a quick summary once a scan has found something, such as how many sets there are and how much space they'd free.
