- ID0 is the first 0x10-bytes from a SHA256 hash.
- ID1 is the SD card CID from the SD card which this directory was originally created on, with each u16 moved around from the original CID.
DCIM - Photos and Videos taken by the Nintendo 3DS Camera application are stored in this directory. Internet Browser image downloads are stored here too.
Note: Playing/Recording (3D) Videos was introduced with update 3.0.0-5. The 3D videos are in .avi format and the video frames use MJPG.
dbs - This contains database files relating to the titles installed on the SD Card. These files are encrypted. For more info, see Title Database
title - Title data for titles installed to the SD Card are found here. All data in this directory is encrypted with a console-unique keyslot. For a list of SD Card titles see the Title list. For more info on the title data structure see Title Data Structure.
Nintendo DSiWare - DSiWare titles are exported here.
Extdata
Additional game data is stored here.
See the extdata page for more extdata info and the extdataIDs list.
All "extra data" under extdata is encrypted. Extdata can't be decrypted with the xorpad fail used for old FLASH saves. All "extra data" files can't be copied to other 3DS SD cards, they are locked to the console.
Private
"Private" data is stored here:
/Nintendo 3DS/Private/<Title ID Low>/
00020400 - Nintendo 3DS Camera 00020500 - Nintendo 3DS Sound
"Private" data for 3DS Sound/Camera are cleartext.
Under the camera priv dir is phtcache.bin, this seems to list the pictures on SD card?
When you want to install and see pictures with 3DS,rename to 8 numbers.mpo and save it on /DCIM .
Under the sound priv dir is: voice/XX/*.m4a. Where XX is 01-10, with sound saved as .m4a.
