 The extension requires read and write access to a directory. A default directory can be used, but it must already exist in order for the extension to operate.
 
 `directory` is the relative or absolute path to the dedicated data storage directory. 
+The default directory is `%ProgramData%\Otelcol\FileStorage` on Windows and `/var/lib/otelcol/file_storage` otherwise.
