Hacking First hacked my 3DS in January 2016. Never deleted anything from my SD card. It's a mess!

Hi!

I would like to clean up my 3DS' SD card because I feel that a lot of files aren't useful anymore, but I don't know what files I can safely delete.

I first hacked it in January 2016 with Emunand9 / rxTools / Menuhax.
Then, in November 2016, Emunand wasn't needed anymore, thanks to arm9loaderhax, so that's what I installed.
At some point I migrated to boot9strap and Luma3DS, and that's what I'm using now.

It seems the Cakes CFW was installed at some point also.

Here is a screenshot of the SD card's root folder:

Could you help me?
Thank you

Just keep the Nintendo 3DS folder, boot.firm, boot.3dsx, and 3ds folder.
