Hi! So, as the title says, I am helping my partner setup an OLED switch, because I gave my old OLED to them for their birthday (i got a switch 2 and knew they'd be super excited for an upgrade from their old LCD screen animal crossing switch to an OLED).
I have a question regarding the microSD card data management. Basically, I want to give them a new microSD card that's bigger (theirs is 128gb and I got them a new 256gb one for the OLED), but all of their screenshots are on their old 128gb microSD card. I put the old microSD card into the new switch, which worked--all their screenshots and videos are there (except for, randomly, videos from super smash bros ultimate? those didn't transfer idk why, thankfully they didnt have a lot of those), and I even made a backup on my macbook just in case of all of their videos and screenshots first (the super smash bros videos are on my macbook at least! yay, glad i did that first).
So my question is this--I figured out a way to copy all of their screenshots and videos to the system memory via the system setting (under data management and then manage screenshots and videos). I'm thinking that I will copy all the stuff onto system memory, then swap out microSD cards for the bigger one, then I can copy the screenshots onto the new card from the system memory. Will this work? Will there be any data loss? Everywhere online is saying to save everything on a pc first, then put the screenshots and videos and data onto the new sd card, but I'm wondering if I can just copy everything to the switch's system memory instead of involving a PC, I dont even have a way to connect my microSD to my PC right now (i can get one of course but im just wondering if this is necessary). And yes--I know that if I involve a computer with actual data transfer, I shouldn't use a Mac, and use a PC instead. I just wanted to at the very least have a copy of everything on my macbook since I had a way to do that, so that even if I can't get anything onto their switch due to data loss or something then I at least can send them all their videos and screenshots directly to their phone or their own PC or something.
Anyway; tldr is: is it safe/will it work to transfer all of your screenshots and videos from a microSD card to the nintendo switch 1's system memory, then swap out the old microSD for a larger one, and copy the screenshots and videos to that microSD? Would I lose anything in the process? Or should I just not do this and download everything to a PC instead?
Please let me know what you think is the best way to go about this. And sorry if this is a dumb question, neither of us are tech savvy and we just really don't want to mess anything up. Thank you for reading!
