What is the recommended way to upload a world save via FTP? I noticed the worlds create three separate folders with suffixes _nether and _the_end. How do I need to break up the normal save folder to populate these separate folders? Or can I upload a zip file and have world management take care of the subfolders? The world is too large to upload through the control panel.

Edit: Never mind, figured it out.

FYI
Step 1) FTP > Upload zip file to root folder
Step 2) In Stipe control panel File Manager extract the zip file

It didn't create the separate folders but I tested the world and it doesn't seem to matter.

Edit 2: It did create the separate folders after I went on the server and tested it.
