Sorry that this is off topic but I'm confused by the purpose of the 2 different files. I see a lot of people asking for .xci. is .xci better?XCI is a game cartridge file, so it is basically saying that you have the physical game cartridge in your switch.
NSP is the digital eshop file, so its saying the game or dlc was bought from the eshop.
XCI- Physical Game
NSP- Digital Game, Updates or DLC
For example, you can download the XCI version of Xenoblade Chronicles 2 and if you wanted to play the new DLC, you would have to find the DLC in NSP format and install the NSP DLC only after you have mounted the Xenoblade Chronicles 2 XCI.
To answer your 1st question, XCI doesn't need installed but instead it needs to be mounted, but NSP does need to be installed.
Depending on whether you are using SX OS or other Switch Modding Methods, it could differ from how XCI are mounted or NSP are installed. Youtube helped me with this though, being that i use SX OS which is simple although I paid 25 dollars for a SX OS License compared to others methods unknown to me that may be free.
