== import.db and title.db ==

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. The purpose of the files in the "dbs" is to archive the list of titles installed on the SD card. These two files are only used for the management of SD Card installed 3DS Titles. The "title.db" file, archives the installed titles aswell as their, names, icons and size. The "import.db" also changes when a title is installed or deleted, but doesn't appear to contain info that the titles "title.db" does. Old and new of the "import.db" and "title.db" can be interchanged without any issues. Essentially the "title.db" acts as the DRM or access rights for downloaded SD card titles. The "import.db" is used during the download/install of SD Card titles, and until the download is complete, it is the only file of the two which is modified.

"'''00000000.tmd'''" - (file name varies depending on title revision) This is the Title Metadata associated with the title, it is encrypted with a per-console key. The decrypted TMD is available on Nintendo's CDN server at "http://nus.cdn.c.shop.nintendowifi.net/ccs/download/TitleIDhere/tmd". Though CDN version of the title TMD has a certificate chain attached at the end of the TMD, so removing it will give you the 1:1 decrypted TMD. After title installation, the important information in TMD is likely stored somewhere, as modifying/deleteing the TMD file, doesn't usually have any effect.

This TMD is likely copied to NAND after installing to SD, as modifying/deleting the SD TMD after title installation has no effect.

'''"00000000.ctx"''' - This file is used only while a title is being downloaded from the eShop, it is deleted after the download is completed

'''"00000000.ctx"''' - This file is used only while a title is being downloaded from the eShop, it is deleted after the download is completed.(Might be moved to NAND after installation is completed?)
