ID0 is the first 0x10-bytes from a SHA256 [[nand/private/movable.sed|hash]]. The installation of [[SD Filesystem|SD Card]] titles was introduced in the [[2.0.0-2]] update and the SD dbs files are encrypted. These files are [[extdata]] images. The NAND extdata images are cleartext, however some of the images contain data encrypted with a console-unique keyslot.

~~There~~ are ~~only two files in~~ this directory~~, for~~ SD card:

These files are stored under this directory:

/import.db

{| class="wikitable" border="1"

"'''title.db'''" - With a fixed size of 0x31E400 bytes, this [[Extdata]] image embeds two almost identical copies(the latter is probably an older backup) of the Title Database. For each installed title, the following information is known to be stored:

"'''import.db'''" - The function of the file is not well understood. It appears to be related to the download/install of titles, as in the progress of downloading titles this file will have changed but the title.db will not be modified until the title has been properly downloaded.

*This file doesn't contain any title specific data which the [[Application Manager Services PXI|AM]] has been noted to use in relation to installed titles, even though this file is modified when titles are installed/deleted. In fact, no matter what titles you install, if you use an old copy of the "import.db" with a recent copy of the "title.db", this creates no noticeable issues.

*This file doesn't contain any title specific data which the [[Application Manager Services PXI|ARM9]] has been noted to use in relation to installed titles, even though this file is modified when titles are installed/deleted. In fact, no matter what titles you install, if you use an old copy of the "import.db" with a recent copy of the "title.db", this creates no noticeable issues.
