How do I choose the Synchronization method for Cloud Library Sync?
One Synchronization method is going to MY PAGE and opening the [CLOUD] tab, then going to [Synchronization method] to select [Synchronize selected music files only] or [Synchronize all music files].

- Synchronize selected music files only
When managing tracks on an external storage device or using only the playlists needed on a laptop, [Synchronize selected music files only] is recommended.
Select this setting to use storage space more efficiently.
By downloading the tracks and playlists needed on the DJ player on rekordbox in advance, the DJ player can be played offline in a location without internet connection.
If you wish to use the Dropbox desktop application when this setting is selected, please see the precautions here.
- Synchronize all music files
To manage all the tracks saved in the storage on a PC/Mac used at home and a PC/Mac used in a studio, etc. and keep them synchronized, [Synchronize all music files] is recommended.
Select this setting if there is enough storage space on each PC/Mac and you wish to maintain the same content on the computers as on Dropbox.
This setting offers the function of linking the Dropbox desktop application and rekordbox.
For details on the Dropbox desktop application, see the information below.
