What is on the preinstalled SD card?
I bought a plain (non-special-edition) Nintendo 3DS XL, turned it on, and followed the initial setup instructions. Once it was all set up, I removed the preinstalled SD card and inserted a fresh 32GB card I purchased for this purpose.
It wasn't until nearly 24 hours worth of play time later that I discovered (by putting it in my computer) that the original SD card had data on it, in the Nintendo 3DS folder. More than 20MB worth.
Now, I didn't download any games prior to swapping cards, I finished the initial setup (connect to Wifi, etc.) and immediately powered it off and replaced the card.
So what am I missing? What data comes on the preinstalled SD card?
Best Answer
I just looked into that SD card the other day actually. On my 3DS, the memory had to do with a "Dinosaur Video" application that I never used nor opened, and the rest was either "update notice" messages or screenshots I had saved.
In other words, nothing important that will hinder your future gaming experience.

Answer 2
At that size It's likely to just be save/cache data stored to the sd card from the system apps when you were setting the system up.
The 3DS may even set up a default file and folder structure on every SD card that is inserted into it.
Around 20MB is nothing significant.
