Note: The question marks from Dummy1 to GetSpecialFileSize on the "available since system version" field are mainly there because I think that most of these are necessary for the main system to function, so theoretically that would mean that since the creation of the 3DS these were available, or since launch if that makes more sense. But because of the peculiar nature of some of the functions, they will remain question marks until they can be confirmed 100%.
=File service=
When access rights are required for a command, at least one of the bits in the process access info specified in the above table for the command must be set. Error 0xD9004676 is returned when a process attempts to use a command which it doesn't have access rights for the command. The exheader access info field is all zero's for most applications. Note that the permissions listed in the above table is for system-version v2.x, therefore permission bit(s) added with newer FIRM may be missing from this.
Each session for fs:USER has separate permissions, initially these are set to all zero's for new fs:USER sessions. The permissions/etc for fs:USER sessions are initialized via [[FS:Initialize]](loaded from the user process exheader).
== Filesystem service "fs:LDR" ==
This service is identical to fs:USER, except [[FS:OpenArchive]] archive 0x2345678E can only be accessed with fs:LDR.

Only two sessions can be opened for this service at a time, hence no other processes can use this due to [[Process_Manager_Services|pm-module]] and [[Loader_Services|loader]] using this.
=File and directory access=
==Files==
File session handles obtained via [[FS:OpenFile]] and [[FS:OpenFileDirectly]] can be used to access files through a service-like interface, despite not being an actual service registered using [[SRV:RegisterService]]. To use this service-like interface, simply call the SendSyncRequest SVC with a file session handle, using the IPC buffer in thread-local storage for parameters and responses, just like you would with a proper service.

Archives listed as not requiring a binary lowpath, use lowpath type [[FS:OpenFile|empty]].
The above permission bitmasks are from v2.x, see the above Services section for how these are handled.
Archives CTR NAND, NAND RO Write FS, TWL NAND, NAND W FS, and CARD SPI FS require the corresponding process exheader access control mount flag to be set, in the exheader for any of the currently running ARM11 processes, for [[Filesystem_services_PXI|FSPXI]]. The access rights checked by [[Filesystem services|FS]] module for archive mounting with fs:USER, are stored in the process' exheader accessinfo.
The CARDSPI archive allows access to the gamecard CARD1 raw savedata flash(aka "cardspi:/" in [[FIRM|Process9]]), the file lowpath must be WCHAR "/". The "NAND W FS" archive allows access to the raw NAND image(aka "wnand:/" in Process9), the file lowpath must be WCHAR "/".

For FS, the file/directory lowpath is a text path in the [[extdata]] filesystem. For FSPXI, the file lowpath is a text path relative to the "/extdata/<ExtdataIDHigh>/<ExtdataIDLow>" directory on SD/NAND, for the cleartext extdata image to mount.

The 0x14-byte lowpath is all-zero for accessing the title's main RomFS.
=== [[RomFS]] ===
Archives 0x3 and 0x2345678E both allow for accessing the [[RomFS#Level_3_Format|level-3 IVFC images]] for RomFS access. The main CXI RomFS is accessible via an all-zero 0xc-byte binary file-lowpath. The update RomFS can be accessed with the first u32 in the binary file-lowpath being set to 0x5. The user must handle parsing the filesystem used in the exposed image itself.
With FSPXI the returned data for RomFS is the entire RomFS section from the NCCH, starting at the IVFC header.
The 0x3 archive is an interface for the 0x2345678E archive with the current process programID+mediatype. The file lowpath is 3-words. These words are written to 0x2345678E-archive file_lowpath+0, with the rest of that lowpath set to all-zero(lowpath is different from archive 0x2345678A). File lowpath:

=SEEDDB=
With [[9.6.0-24|9.6.0-X]] new [[System_SaveData]] with saveID 0001000F was added, this seems to be handled by FS-module itself, probably via the new service-cmds added to fsuser. [[Home Menu]] and [[NIM_Services|NIM]] module have access to those commands.
The SEEDDB savedata contains the title-unique seed-data used for the new [[NCCH]] keyY generation added with FIRM [[9.6.0-24|9.6.0-X]].
