Can you reset the nether? [duplicate]

To answer your question, you can reset the nether, but the new one that will generate will be the same as the old one, except without any changes you may have made. (This could be used to cheat, go to the nether, gather resources, reset the nether, gather the same resources in the same location, and so on…) To reset the nether, go to

C:\Users\<your windows username>\AppData\Roaming\.minecraft\saves\New World

on Windows or

~/Library/Application Support/minecraft

on OS X. Next go to the "/saves" folder, and then into the folder that corresponds with the world in which you want to reset the nether. Usually the folder will have the same name as the world it corresponds with. Finally go to the "/DIM-1" folder and delete anything inside. Next time you enter the nether, minecraft will reset the nether to how it was before you made any changes to it.

Note: This answers the question "how to reset the nether", but this just erases any changes you may have made to it, thus "reset". You can't really use this to find nether fortresses.

You cannot reset the nether without making a new world.

There always are nether fortresses in the nether so keep looking. I would install a mini-map mod so you can way point your portal so you can venture further without the worry of loosing your portal. Perhaps the morph mod or another mod so it can allow you to fly so you can travel faster.

Do note that they can be affected by the Generate Structures option, so make sure that's on (It's on by default.)

Resetting the nether won't change the position of fortresses, as they are based on the seed which you cannot change without messing other things up. You can use some tools on the internet that show you the exact position of all the fortresses.

I would recommend Amidst: https://github.com/toolbox4minecraft/amidst/releases

Or if you don't want to install something to your computer, here's a handy online tool (be sure to read the "How To Use" section at the bottom): http://chunkbase.com/apps/nether-fortress-finder

You can actually reset the nether. Make a new world in creative and go into the nether. If it has a fortress then leave the nether, exit the game then go to C:\Users\username\AppData\Roaming.minecraft\saves then click on the creative world that you created then go to DIM-1 folder copy the contents then move them to your survival world or any other world. Make sure the world you are moving it into you delete all of the contents in the DIM-1 folder.

Actually, yes you can, in your settings of your world you can find two options (reset nether) and (reset end) you can try looking for those two buttons
