Internal migration flag for download path storage
Most settings are written to %APPDATA%\qBittorrent\qBittorrent.ini (an INI file), not the registry. The key above is one of the few values qBittorrent stores in the registry.
All meaningful configuration (download paths, speed limits, RSS feeds, WebUI settings) is stored in %APPDATA%\qBittorrent\qBittorrent.ini, not the registry.
Torrent metadata and the download queue are stored in %LOCALAPPDATA%\qBittorrent\BT_backup\.
The portable version stores its INI alongside the executable and creates no registry entries.
magnet: URI handler registration is optional during install; if enabled, it creates HKCU\Software\Classes\magnet (or HKLM\SOFTWARE\Classes\magnet for system-wide).
