A folder-sync copy/delete on a large LOCAL directory crawled at ~1 file/sec. The cost is not the file operation (raw unlink runs hundreds-thousands/sec) but the source panel's directory watcher: each changed file fires a watcher event, and once >100 (or >25% of the listing) pending changes accumulate, TFileView reloads the WHOLE directory (ufileview.pas), rate-limited to once per second. During a bulk operation this full reload keeps re-firing, so the whole thing becomes O(n²) and stalls — the sync runs the operation inline on the GUI thread, so each reload directly blocks it. Add TFileView.SetWatcherEnabled (public wrapper over the existing protected EnableWatcher, plus one reconciling reload on resume) and have the sync dialog suspend both source panels' watchers around the copy/delete run and the compare-grid delete buttons, restoring them via try/finally. Operations now proceed at filesystem speed; the panels refresh once at the end. Cross-platform: the reload path is platform-agnostic and is fed by inotify (Linux), ReadDirectoryChangesW (Windows) and FSEvents (macOS) alike.
