The debug info can be seen at chrome://files-internals/debug.json ChromeOS' Files app uses FileSystemURLs whose mount_type() is very often kFileSystemTypeExternal. It also serializes FileSystemURLs as strings for IPC (e.g. between ash and Fusebox, or ash and lacros). When debugging the ChromeOS Files app, it can be useful to know the list of registered ExternalMountPoints.
