Where Google Earth Pro keeps its logs
Google Earth Pro logs to %USERPROFILE%\AppData\LocalLow\Google\GoogleEarth on Windows. 1 other Windows log location is recorded below.
Google Earth Pro logs to ~/Library/Application Support/Google Earth/ on macOS. 1 other macOS log location is recorded below.
Google Earth Pro logs to ~/.googleearth/ on Linux.
Paths are printed exactly as Google Earth Pro 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.
