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 "/".

=== [[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:
