Get .desktop files from $XDG_DATA_HOME/applications (default to $HOME/.local/share/applications) followed by $XDG_DATA_DIRS/applications (default to /usr/local/share/applications followed by /usr/share/applications). Order is important!
Get .desktop files from subdirectories of the ones mentioned above
Each .desktop file has a desktop file id (path relative to applications directory, with "/" replaced by "-"), only first .desktop file with a specific id found is used (hence why the order above matters). This allows users to locally override system .desktop files.
e.g. if there is a ~/.local/share/applications/steam.desktop and /usr/share/applications/steam.desktop they both have the same id so the first one will be used rather than the second one
