This article is a stub. You can help WiiBrew by expanding it.

The filesystem can be directly accessed through "/dev/fs".

There are several IOS functions for FS like Delete/Create/List/Rename/.. .

Files can be directly opened with IOS_Open("/tmp/data.bin",1);

The root folder contains these subfolders, some of which have their own pages:

/tmp

/meta

/import

/shared1

/shared2

/title

/ticket

/sys

/wfs (4.3 only)

Ioctl listing

Request number Name input output notes
0x1 Format - - Can only be called by UID 0.

Deletes the entire FS, not like the System Menu button. Will probably brick the console. Do not use!

0x2 GetStats - 0x1C bytes: 7 u32's: cluster size, free clusters, used clusters, bad clusters, reserved clusters, free inodes, used inodes.
0x3 CreateDir 0x4A bytes: 4 for owner ID, 2 for group ID, 0x40 filename, 1 for each owner/group/other permissions, 1 for attributes. 0
0x4 ReadDir Directory name (0x40), Max file count (0x4) File names (0x13*maxFileCount), File count (0x4)
0x5 SetAttr See CreateDir input. -
0x6 GetAttr 64 bytes for filename See CreateDir input.
0x7 Delete 64 bytes for filename -
0x8 Rename 64 bytes for source, 64 bytes for destination -
0x9 CreateFile See CreateDir input. Owner ID and group ID will not be used. 0
0xa SetFileVerCtrl ? ?
0xb GetFileStats - 8 bytes: 4 bytes for file size, 4 bytes for seek position
0xc <ioctlv> GetUsage 64 bytes for filename 4 bytes for used clusters, 4 bytes for used inodes
0xd Shutdown - - Disables the NAND and refuses any further IPC requests with error -119.
0xe <ioctlv> ????? List of paths for the files to create. Last vector is an array of u32's with the file sizes. - Creates and allocates a list of files in one go.

Somehow not used by ES, despite probably being the one to benefit the most from such a function.

/dev/fs error codes

Error code POSIX equivalent notes
-1 EACCES Permission denied (IOS error)
-2 EEXIST File exists (IOS error)
-4 EINVAL Invalid argument (IOS error)
-6 ENOENT File not found (IOS error)
-8 EBUSY Resource busy (IOS error)
-11 ? ECC error (corrected)
-12 EIO ? ECC error (uncorrectable)
-13 EIO ? This block is bad
-22 ENOMEM Alloc failed during request (IOS error)
-101 EINVAL Invalid argument (again? Returned e.g. by /dev/fs IOCtls)
-102 EACCESS Permission denied
-103 EIO? returned for "corrupted" NAND
-104 ? Filesystem not initialized(?)

ES will call Format if GetStats returns this error code.

-105 EEXIST File exists
-106 ENOENT File not found
-107 ENOSPC? Filesystem is full (no free inodes)
-108 ENOSPC Filesystem is full (no free clusters)
-109 ENFILE Too many fds open (16; includes /dev/fs)
-110 ENAMETOOLONG? Max directory depth exceeded (8)
-111 ETXTBSY Trying to delete a currently open file
-112 ? This block is bad (=-13)
-113 ? ECC error (corrected) (=-11)
-114 EIO? ECC error (uncorrectable) (=-12)
-115 ? File is not empty

(?? both SetAttr and SetFileVerCtrl complain about this)

-116 ? Cluster has been tampered with[check]
-117 - unknown error
-118 EBUSY Resource busy
-119 ESHUTDOWN The filesystem has been shut down
