@EverclearBoy - The ebc files go in order as you install them. You don't have to put the same stuff in your first .ebc file that I put in mine. But you should first install the biggest stuff like worlds first. Then the second largest file sizes are the compilations and combined sets. Third in size are the individual sets, and lastly, the individual stuff.
If you plan to get a world or compilation or set later, and you want to leave room for it in a certain .ebc file, that is fine. Otherwise, my spreadsheet is just an example of how I did it with the links or urls to make downloading and tracking easier.
