All "extra data" under [[extdata]] is encrypted. Although these files use 0xFF blocks similar to FLASH [[Savegames|saves]], extdata can't be decrypted with the xorpad fail like FLASH saves. All "extra data" files can't be copied to other 3DS SD cards, they are locked to the console.

With the introduction of the June update the folder structure changed slightly. You will now find "dbs" and "title" folders located in /Nintendo 3DS/<SomeID>/<SomeID>/ along with the extdata folder. "dbs" contains two files, import.db and title.db - usage currently unknown. Since titles with their title and extdata dirs deleted/renamed are still displayed by home menu, the dbs files likely contain the icons for titles on sdcard.

"dbs" contains two files, import.db and title.db - usage currently unknown. import.db seems to contain data from DSiWare SRLs. The data at the beginning of the file is encrypted, but the rest is cleartext. This file is always 3.1MB, thus this doesn't contain the whole SRL for most DSiWare. The data stored here is not ordered the same way as the src SRL: ARM7 code, ARM9 code, and data are mixed together. The file can contain data from DSiWare that wasn't installed, only listed on the src DSi for DSiWare transfer.(This file is likely some temporary data storage used for DSiWare install etc)
title.db seems to be encrypted.
/title/00040000/ Contains eshop downloads (can someone verify these and add for different regions?):
