Line 79: − − .[[CIA]] - CTR Importable Archive - This format allows the installation titles to the 3DS. CIA files can contain [[NCCH]] files for installation to either the [[SD Filesystem|SDMC]] or CTR NAND. CIA files can also contain .SRL files (format for DS(i) executable images) for installation to the TWL NAND of the 3DS. − − .[[TMD]] - Title Metadata - The format is used with installed/installable titles. Notably they are found in .[[CIA]] files (plain text), on the [[SD Filesystem#title|SD card]] (encrypted), NAND (encrypted) and on Nintendo's CDN (plain text). Line 80:
Line 85: − − .[[SD Filesystem#title|CTX]] - When beginning eShop app downloads, this file is created. Later this file is written with actual data. When the download is completed, the file is deleted from SD card.(This might then be moved to NAND) This is encrypted with a per-console key. It contains a signed cert followed by unknown data. It is only 1.50kbyte. Here is an example.[http://dl.dropbox.com/u/37418652/00000000.ctx]

.CDI - CTR Development Image - CDI files are system processes which other types of applications depend on for access to various other lower level functions. CDI are normally the same titles as listed in a CXI header's dependency list, they are just compiled to a different format. The difference is that CDI is used for a different (test) environment. They're loaded into hardware debugger's memory, along with the 2 cores in order to execute.
