Soft Dedup (natural behavior) If a new File Explorer window navigates to a folder that's already open elsewhere, simply bring the existing window to front. Do NOT close any window (no flicker, no accidental kills). Hold a configurable modifier key (Shift by default) to bypass dedup and allow another window. Extras Grace delay so the new window can finish navigation (/select,filename etc.) before we decide. Special handling for the Downloads known folder (shell:Downloads and its GUID). If you ever want closing behavior, switch DuplicateAction in settings. Notes Dedup is window-level. Tabs inside the same Explorer window are not merged (Windows API doesn't expose tab list here). Virtual / non-file-system locations are ignored, except Downloads which is resolved to its physical path.
Gentler dedup, fewer "restart-like" hiccups: - Double stability checks (new + existing window). - Gentle close: minimize first, then async WM_CLOSE. - Never close last window (per-process) option. - Rate limiter: cap closes/min; fall back to focusing. - Special handling for Downloads (shell:Downloads + GUID). Fix 1.7.0: - Only the truly NEWER window (by firstSeenTick; tie → larger HWND) is allowed to resolve the duplicate in a scan cycle. This prevents the "both windows get closed" race.
