yo do u guys know how to transfer totk save files to like a external hard drive or to a laptop?

i wanna start speedrunning 1.0/1.1 so i dont wanna lose the data of my casual playthrough.

You need a modded switch for that, you can use checkpoint to extract the save then move those files from the SD card to your pc. I'm not sure if it's possible without a modded switch

u save on the nintendo online cloud and restart ur switch for totk 1.0/1.1 and transfer the data in the main account and create an annother account for speedruns but don't forget to remove the automatical updates but the problem is that i don't know if u can transfer the data while keeping 1.0/1.1 updates
