How can I change installation folder?

I wanted to know if you can change the folder where the files are saved, because I have an external hard drive

You can not change the folder that the installer installs to. You can change the folder that the nand is saved in in yuzu settings, which contains the majority of things that might take up a lot of space such as installed updates and dlc.

If that is not enough for you then you can manually download yuzu instead of using the installer, extract it somewhere and create a folder called user in the folder with yuzu.exe that will make it so everything that would be saved in %appdata%\yuzu will be saved in the user folder instead so it’s completely portable. That means there will be no automatic updates though.

But will the emulator be updated even if I download it manually?

Ah ok I didn’t understand the end of your message, sorry I’m Italian
