# While you want to listen to lossless music on your computer you may not be able to also listen to it mobile because
|
|
# it takes too much space. A 32GB-SDCard does not suffice for your full music library so you only have the options to
|
|
# either only hearing to a subset mobile or converting the music to a lossy format. This script is for the second
|
|
# option.
|
|
# * Of course you don't want the lossy files on your computer because you already have your perfect lossless music there.
|
|
# * If you extend your music library you want a simple way to also have them mobile.
|
|
# * You don't want to convert already converted music twice
|
|
# This script synchronizes a lossless library folder (e.g. your music folder on your computer) to a lossy library
|
|
# folder (e.g. the music folder of your mobile device) by checking if for all music files in your lossless folder there
|
|
# is a converted version in your lossy folder. If this is not the case the file is converted. On the other side it
|
|
# checks if you still have the lossless file for each lossy file in your library, otherwise this file is removed (so
|
|
# removing a file from your lossless library also removes it from your lossy library)
|
|
#
|
|
# You can use your own commands for converting specific files. These commands have to convert a single file (check the
|
|
# commands-array).
|
|
#
|
|
# The configuration is done with the from_path and the to_path, as well as with the commands-array.
