How to move saved data game from one pc to another

Delete the file first or move it elsewhere.

How do move it elsewhere?

Let me try to make it clear, ignore my last comment. you are trying to copy a save from one(1) pc to another(2), correct?

on the (1) pc open citra and right click on the game you want to copy the save and ‘Open Save Data Location’.

For pokemon ultra sun that will be C:\Users\%username%\AppData\Roaming\Citra\sdmc\Nintendo 3DS\00000000000000000000000000000000\00000000000000000000000000000000\title\00040000\001b5000\data\00000001

as mentioned before the folder 00040000 is where all save games folder are located (much like some pc games store its save file on \Documents\My Games)

when you opened the save data location from pokemon ultra sun you can see that the folder that opened was: 00040000\001b5000\data\00000001

meaning that the folder 001b5000 is the folder you want. copy this folder.

on your (2) pc, open the folder C:\Users\%username%\AppData\Roaming\Citra\sdmc\Nintendo 3DS\00000000000000000000000000000000\00000000000000000000000000000000\title\00040000

paste the 001b5000 inside.

Sorry my (2) one is a laptop and not a pc, what link should i do

if its windows you simply open the folder i mentioned. if its a mac open the folder:
~/.local/share/citra-emu/sdmc/Nintendo 3DS/00000000000000000000000000000000/00000000000000000000000000000000/title/00040000/
