My DJ Cloud works with sync folders, similar to Dropbox or Google Drive.
To backup your files, click the button to add a sync folder in the My DJ Cloud app, then select the folder that contains your all your music. You can add as many folders as you like, even from external and thumb drives.
Any change that's made to files in your sync folders, from any application, will instantly be synced to the cloud, including (but not limited to) filename, path, id3 tags, metadata, etc.
We currently support the following audio file types:
.mp3, .m4a, .m4p, .aif, .aiff, .aifc, .wav, .wave, .flac
