I am trying to free up space. And i have tried shitloads with my new3ds which i dont all quite remember.
Which im sure must have left traces.
Now with a9HL and luma everything has become more tidy. I dont have an emunand anymore also.
But i think i still have lots of useless files.
Could someone plz point out the files that are safe to delete?
Many thanks

Have a look at the end of Plailect's guide, it will tell you which files are necessary and which are not. Basically you want the folders Nintendo 3DS, luma, and 3ds (for homebrew files) and arm9loaderhax.bin to boot a9lh with. Make sure you back up your files somewhere in case in the future you find one of them was necessary.
