Archives listed as not requiring a binary lowpath, use lowpath type [[FS:OpenFile|empty]].
 
 
 
 
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 "/".
