The structure of [[nand/title]] appears to be exactly the same as [[SD Filesystem|SD]], except savegames are stored under the [[System SaveData|nand/data/<ID0>/sysdata]] directory instead.

The sub-directory name under [[nand/data]] is the SHA256 hash over the [[nand/private/movable.sed|movable.sed]] keyY. This nand/data/<ID0> directory is the NAND equivalent of the "sdmc/Nintendo 3DS/<ID0>/<ID1>" directory, however the data contained here is stored in cleartext. The movable.sed keyY is only used for AES MACs for nand/data/<ID0>. The nand/data/<ID0>/extdata directory contains the shared [[extdata]], and is structured exactly the same way as SD extdata.

~~The "nandrw" [[FS:OpenArchive|archive]] is mounted at "nand:/rw/", while the "nandro" archive is mounted at "nand:/ro/".~~
