BK00 and SD00 in the emuMMC SD Folder

[KoalaOperative]

Hi everyone,

Long time lurker, first time poster.

So I was looking in to getting some more space available in the SD card on my Switch. Its modded with a chip, and everything works perfectly.

My current SD is 256GB, and I saw that the backup folder was freaking huge. Since I have it on 2 external drives, and on the cloud, I was researching and figured it was fine to delete it.

The question is: in my /emuMMC/ folder I have the following files/directories:

BK00
SD00
emummc.ini

What is this BK00 folder? From what I understand it is a Backup folder. Is that correct? Would it be safe to delete it? Should I keep a copy somewhere safe?

Thanks in advance!

That is your file based emunand, it is stored on the SD card.

So... Safe to delete it? No consequences?

No they are your emunand, if you delete it you lose your emunand.

I get that with the SD00 folder and the .ini file, obviously

I was asking specifically about the BK00. Is it necessary to keep it in the SD?

That is your backup

That is your backup

I know. The question is: do I need to keep the backup (BK00) on the SD, or can delete it and keep a copy on my PC for future issues?

What is the size of the folder 29.2GB? or it is double like 58.4?

I believe they are backup, since have boot0 and boot1, but you have to figure what files on your SD is file base emunand.

They probably don't use file based emuNAND, most people don't.
