My World is gone

Is the world save file still in the .minecraft folder? If so, could you attach it here? If the filesize is too large, you can upload it somewhere else and link to it here.

how do i do that?

Go to your .minecraft folder, enter the saves folder, and check if the world file of the world that disappeared exists. If it does, please zip it and attach it here or use a cloud service of your choice to provide it to us.

The World is still there i zipped it but i cant attach it here it says the folder is too big

Then upload it somewhere else and share the link.
