hmm im assuming you are on windows

so you have to right click it then click extract all

then extract it to downloads or something

then click it then ctrl+c

then click windows, then type "run" then hit enter

then type %appdata% then click enter

then click .minecraft

then click saves

then paste it (ctrl+v)

sorry i dont have time to fully detail it

ill do a video recording of myself doing it though

If you have the world file, in zip:

1. Extract File
2. Drag the extracted file into your .minecraft/saves folder

If you have the world file as a folder

1. Drag the folder into .minecraft/saves folder

Once you downloaded the file, open your downloads and right click on the file and hit extract all. Then, type "%appdata%" into your windows search bar. From there, click on the folder ".minecraft" Then click on "saves". Drag the extracted file into saves. Reload your Minecraft and you should have the end practice.
