2 log locations · Windows
Google Drive Desktop logs to %LOCALAPPDATA%\Google\DriveFS\Logs\ on Windows. 1 other Windows log location is recorded below.
Paths are printed exactly as Google Drive Desktop 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.
