If the client process lacks the relevant permission for any of the above partition IDs, error 0x2EE202 is returned.

[[NCA]]s stored in NAND are raw, identical to the data readable with [[Content_Manager_services#ReadEntryRaw]].

The filenames for saveimages is just "<lower-case hex u64 saveID>". SYSTEM-partition saveIDs are specified by [[Filesystem_services|FS]] commands, while USER-partition saveIDs are determined by FS-module internally. The high u32 of the saveID is normally either 0x00000000 or 0x80000000.

The saves for all non-system applications, regardless of where the application is located(storageID), is stored here. Each user account which has savedata has a separate saveimage. Save-common for an application is presumably a separate saveimage too. Every saveimage here is ''only'' for applications.
