#
# Local file browser. Presents files from configured directories.
# This is not what Streamtuner2 is meant for. Therefore this is
# an optional plugin, and not overly well integrated.
#
# Bugs:
# Only loads directories on startup. Doesn't work when post-activated
# per pluginmanager2 for instance. And LANG=C breaks it on startup,
# if media directories contain anything but ASCII filenames.
#
# Currently does not play files with UTF characters on Windows.
#
# If your player doesn't play local files try unchecking "Convert file path to 'file:///' style URL". (Might happen on Windows when not using VLC.exe).
# When using VLC however it must be checked.
#
# After checking/unchecking restart Streamtuner2 for recollecting the local files.
