"'''XXXXXXXX.app'''" - (There is no pattern to the file name) These files are [[NCCH]] files, where the entire file is encrypted with a per-console key. There can be more than one NCCH in this directory, as seen with .[[CCI]] files, the game executable ([[CXI]]) can be accompanied with additional non-executable NCCH files ([[NCCH#CFA|CFA]]) such as the electronic manual and DLP Child containers. Determining the function of the encrypted NCCH, is done by finding the Content Index of the "XXXXXXXX.app" file in the title's TMD(see above for retrieving decrypted TMD), interpreting the Content Index is as follows:

"'''XXXXXXXX.app'''" - (There is no pattern to the file name, however for a given title, ".app" file names are not reused) These files are [[NCCH]] files, where the entire file is encrypted with a per-console key(this is on top of the encryption of the NCCH contents). There can be more than one NCCH in this directory, as seen with .[[CCI]] files, the game executable ([[CXI]]) can be accompanied with additional non-executable NCCH files ([[NCCH#CFA|CFA]]) such as the electronic manual and DLP Child containers. Determining the function of the encrypted NCCH, is done by finding the Content Index of the "XXXXXXXX.app" file in the title's TMD(see above for retrieving decrypted TMD), interpreting the Content Index is as follows:

"'''XXXXXXXX.cmd'''" - (file name starts with 00000001.cmd and increases with an increment of "1" for each title version the 3DS is introduced to) This file contains data taken from the title's [[TMD]] during install. The data includes the title ID, file names and hashes (possibly sizes aswell) of the .app files to prevent tampering. This file appears to be signed, and keeps a record of it's true file name. In addition it is also encrypted with a per-console key.

"'''XXXXXXXX.cmd'''" - (file name starts with 00000001.cmd and increases with an increment of "1" for each title version the 3DS is introduced to) This file contains data taken from the title's [[TMD]] during install. The data includes the title ID, file names and hashes (possibly sizes aswell) of the .app files to prevent tampering. This file appears to be signed(or contains a hash of itself), and keeps a record of its true file name(alternatively it could store the title version, which can be used to determine its true file name). In addition it is also encrypted with a per-console key.

'''"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?)
