Where qBittorrent keeps its logs

qBittorrent logs to %LOCALAPPDATA%\qBittorrent\logs\qbittorrent.log on Windows.

Paths are printed exactly as qBittorrent writes them. Environment variables like %LOCALAPPDATA% and $XDG_STATE_HOME are never expanded, so a path can be pasted straight into a shell. Where a path differs between installer types or shipping flavours, each one is racked as its own card below - why that happens.
