Whilst current sets are only available on the current device, these can be saved and then later loaded from set files.
All set files are stored in the /OpenSong/Sets/ folder. To better help organise your sets, OpenSongApp allows you to use categories. These are simply appended as text to the beginning of the set file name (making them compatible with the desktop version of OpenSong). Selecting a category will find all matching sets and display them on the screen. The MAIN category is for sets that haven't specified a category.
Click on the set to load in. If you click on more than one set, they will be merged in order of clicking on them. Once you have selected the appropriate set(s), click on the Load button. This will overwrite your current set with the contents of the sets loaded in.
