Where is the directory for the Multiverse worlds?

  • Hello, so before, on an old server, I used to be able to replace a newly added world with another one (for example, I made a random world in multiverse, went to the worlds tab on aternos, and replaced the world with a custom one). Still, when trying the same method in my new server, there are only 3 worlds. which are the default ones; I can't find the newly created worlds. any help would be appreciated.
