World won't upload to server

Hi, I keep trying to upload my world, it appears like it successfully uploaded, but when I log on it's the same world as before. The gear moves and the shaded part moves to completion, then nothing happens after that (not sure if that's how it supposed to work)

I already looked at the video of how to upload worlds/make backups, and the world works in single player

Here's the world: http://www.mediafire.com/file/72xxldx1ob8ddtr/world.zip

(one thing i noticed about it is that it just has the world, without the world_nether or DIM-1 or anything like that)

Also, the interface on aternos is split into world, world_nether, and world_the_end, would that have to do anything to it? And if I uploaded only to the world section, would that change the other two worlds?

Thanks for your help!

You're trying to upload a complete server folder, but it is only possible to upload single worlds.

Oh, how do I upload just a single world? I got the file from downloading the world from aternos as a backup. (around 2 years ago though)

Every .zip world you get from your Minecraft has 3 worlds: Overworld (world), Nether (world_nether), and the End (world_the_end). Depends on where you want the world to be added on.

Also, before you upload your world, make sure to stop your server first then do it

It didn't have three worlds inside though D:

Sorry, it seems I mixed up two support cases.

The world looks okay.

What's your Aternos username?

Oh, its okay: Phobiax
