|-
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
| 0x7 || CanDeleteSaveData || 0x8000000000000060 || [[#DeleteSaveDataFileSystem]], RegisterSaveDataFileSystemAtomicDeletion
 
|-
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
| 0x8 || CanCreateSystemSaveData || 0x8000000000000028 || CreateSaveDataFileSystemBySystemSaveDataId
 
|-
May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.

== OpenFileSystem ==
== GetSaveDataCommitId ==
Takes a type-0x19 input [[#ContentPath]] and a [[#FileSystemProxyType]] as parameters. Returns an [[#IFileSystem]].
Takes an input u8 and u64, returns an output u64.


[2.0.0+] This function was removed.
== SetSdCardEncryptionSeed ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.


== SetCurrentProcess ==
[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is all-zero except for the byte at offset 0x20. This byte is set to 1 by NS if the SD card has been mounted successfully and is subsequently passed to SetSdCardAccessibility.
Takes a pid-descriptor.


== OpenFileSystemWithPatch ==
== OpenAccessFailureDetectionEventNotifier ==
Takes an input [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
Takes 8-bytes of input and returns an [[#IEventNotifier]].


Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
[8.0.0+] Now takes an additional 8-bytes of input.


Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
== SetSaveDataSize ==
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.


== OpenFileSystemWithId ==
These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].


The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
These variables don't seem to be actually used anywhere else (?)


The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
== SetSaveDataRootPath ==
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);


May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.
This path is normally all-zero. When this path is non-zero, the internal OpenSaveDataFileSystem function will create a DirectorySaveDataFileSystem if the target save is a user-save + a directory exists, instead of the normal savedata filesystem object.


The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
== SetGlobalAccessLogMode ==
Takes an input u32.


After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
== SetGlobalAccessLogMode ==
Takes an input u32.


When [[#FileSystemProxyType]] is '''Meta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA [[NCM_services#ProgramId|ProgramId]], then an error is thrown on mismatch.
== GetGlobalAccessLogMode ==
Returns an output u32.


== OpenBisFileSystem ==
GlobalAccessLogMode is normally 0.
Takes a type-0x19 input buffer string and a [[#BisPartitionId]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].


Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.
== OutputAccessLogToSdCard ==
Takes a type-0x5 input buffer.


== OpenBisStorage ==
The input buffer is the string to output to the log. User-processes normally include a newline at the end.
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.


== InvalidateBisCache ==
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].


== DeleteSaveDataFileSystem ==
When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
Takes an input u64.


== CreateSaveDataFileSystem ==
The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).
Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct which governs creation of a saveMeta file.


Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060 meta file size, +4 u8 = 1 meta index which dictates meta file name.
== GetProgramIndexForAccessLog ==
No input, returns two 32-bit values "version" and "program_index".


Creates non-system savedata.
== OpenMultiCommitManager ==
No input, returns an output [[#IMultiCommitManager]].


== CreateSaveDataFileSystemBySystemSaveDataId ==
== OpenBisWiper ==
Takes a 0x40-byte [[#SaveDataAttribute]] and a 0x40-byte [[#SaveDataCreationInfo]].
Takes an input u64 size and a TransferMemory handle. Returns an output [[#IWiper]].


Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.
= IStorage =
This is "nn::fssrv::sf::IStorage".


== OpenGameCardStorage ==
This is the interface for a raw device, usually a block device.
Takes two input u32s (gamecard handle, partition ID), and returns an [[#IStorage]] for the [[Gamecard_Format|partition]].


== OpenGameCardFileSystem ==
{| class="wikitable" border="1"
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].

Mounts savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.
= IFileSystem =
This is "nn::fssrv::sf::IFileSystem".


== OpenReadOnlySaveDataFileSystem ==
There are two main implementations of this interface:
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]], and returns an [[#IFileSystem]].


Mounts SaveData as ReadOnly.
* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.


== ReadSaveDataFileSystemExtraDataBySaveDataSpaceId ==
There are two adapter classes to convert between these interfaces:
Takes an input u8 [[#SaveDataSpaceId]], an input u64 saveID, and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].


== ReadSaveDataFileSystemExtraData ==
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
Takes an input u64 saveID and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.


== OpenSaveDataInfoReader ==
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
No input, returns an output [[#ISaveDataInfoReader]].
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.

[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is all-zero except for the byte at offset 0x20. This byte is set to 1 by NS if the SD card has been mounted successfully and is subsequently passed to SetSdCardAccessibility.

[8.0.0+] Now takes an additional 8-bytes of input.
== ReadSaveDataInfo ==
Takes a type-0x6 output buffer. Returns an output u64 for total output entries. This buffer contains an array of [[#SaveDataInfo]].


== SetSaveDataSize ==
This is used to get [[#SaveDataInfo]] for all savedata on the system (or all savedata for the current [[#SaveDataSpaceId]]). When used multiple times, it will resume reading where it left off, until no more entries are available (in that case the out u64 is value 0).
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.


These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.
= IDeviceOperator =

== OutputAccessLogToSdCard ==
Takes a type-0x5 input buffer.
 
The input buffer is the string to output to the log. User-processes normally include a newline at the end.
 
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
 
When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
 
The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).
 
== GetProgramIndexForAccessLog ==
No input, returns two 32-bit values "version" and "program_index".

= IFileSystem =
This is "nn::fssrv::sf::IFileSystem".
 
There are two main implementations of this interface:
 
* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.
 
There are two adapter classes to convert between these interfaces:
 
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.
 
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.
