  1. ^ IBM introduced JFS with the initial release of AIX Version 3.1 in 1990. This file system now called JFS1. The new JFS, ported from OS/2 to AIX and Linux, was first shipped in OS/2 Warp Server for e-Business in 1999. It was released as JFS2 on AIX 5L.
  2. ^ Microsoft first introduced FAT32 in Windows 95 OSR2 (OEM Service Release 2) and then later in Windows 98. NT-based Windows did not have any support for FAT32 up to Windows NT4; Windows 2000 was the first NT-based Windows OS that received the ability to work with it.
  3. ^ a b These are the restrictions imposed by the on-disk directory entry structures themselves. Particular Installable File System drivers may place restrictions of their own on file and directory names; and particular and operating systems may also place restrictions of their own, across all filesystems. MS-DOS, Microsoft Windows, and OS/2 disallow the characters \ / : ? * " > < | and NUL in file and directory names across all filesystems. Unix-like systems disallow the characters / and NUL in file and directory names across all filesystems.
  4. ^ a b c d e For filesystems that have variable allocation unit (block/cluster) sizes, a range of size are given, indicating the maximum volume sizes for the minimum and the maximum possible allocation unit sizes of the filesystem (e.g. 512 bytes and 128 KB for FAT — which is the cluster size range allowed by the on-disk data structures, although some Installable File System drivers and operating systems do not support cluster sizes larger than 32 KB).
  5. ^ a b "Maximum CP/M-80 2.2 volume size?", comp.os.cpm, Google Groups, retrieved 2009-10-09
  6. ^ SFS file system
  7. ^ a b c d e f g h i Depends on whether the FAT12, FAT16, and FAT32 implementation has support for long filenames (LFNs). Where it does not, as in OS/2, MS-DOS, Windows 95, Windows 98 in DOS-only mode and the Linux "msdos" driver, file names are limited to 8.3 format of 8-bit characters (space padded in both the basename and extension parts) and may not contain NUL (end-of-directory marker) or character 5 (replacement for character 229 which itself is used as deleted-file marker). Short names also do not normally contain lowercase letters. Also note that a few special names (CON, NUL, LPT1) should be avoided, as some operating systems (notably DOS and windows) effectively reserve them.
  8. ^ a b c d e f g h i j k l m n o p q r s t u v w x y z In these filesystems the directory entries named "." and ".." have special status. Directory entries with these names are not prohibited, and indeed exist as normal directory entries in the on-disk data structures. However, they are mandatory directory entries, with mandatory values, that are automatically created in each directory when it is created; and directories without them are considered corrupt.
  9. ^ a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad The on-disk structures have no inherent limit. Particular Installable File System drivers and operating systems may impose limits of their own, however. MS-DOS does not support full pathnames longer than 260 bytes for FAT12 and FAT16. Windows NT does not support full pathnames longer than 32,767 bytes for NTFS. Most Windows programms will fail when full path exceeds 255 characters (including Explorer and CMD.EXE). Linux has a pathname limit of 4,096.
  10. ^ See manual http://wwwlehre.dhbw-stuttgart.de/~helbig/os/v6/doc/V/fs.html
  11. ^ The actual maximum was 1,082,201,088 bytes, with 10 direct blocks, 1 singly indirect block, 1 doubly indirect block, and 1 triply indirect block. The 4.0BSD and 4.1BSD versions, and the System V version, used 1,024-byte blocks rather than 512-byte blocks, making the maximum 4,311,812,608 bytes or approximately 4 GB.
  12. ^ Table "Limits" states a maximum of 255 Unicode characters for the filename [1]

  14. ^ "msdn TexFAT File Naming Limitations". 2009-10-14.
  15. ^ While FAT32 partitions this large work fine once created, some software won't allow creation of FAT32 partitions larger than 32 GB. This includes, notoriously, the Windows XP installation program and the Disk Management console in Windows 2000, XP, 2003 and Vista. Use FDISK from a Windows ME Emergency Boot Disk to avoid. [2]
  16. ^ As Mac OS X is a Unix-like system, which supports : in file names, and which uses / as a pathname component separator, : in file names is represented on disk in HFS and HFS+ as /.
  17. ^ The "." and ".." directory entries in HPFS that are seen by applications programs are a partial fiction created by the Installable File System drivers. The on-disk data structure for a directory does not contain entries by those names, but instead contains a special "start" entry. Whilst on-disk directory entries by those names are not physically prohibited, they cannot be created in normal operation, and a directory containing such entries is corrupt.
  18. ^ This is the limit of the on-disk structures. The HPFS Installable File System driver for OS/2 uses the top 5 bits of the volume sector number for its own use, limiting the volume size that it can handle to 64 GB.
  19. ^ a b This is the limit of the on-disk structures. The NTFS driver for Windows NT limits the volume size that it can handle to 226 TB and the file size to 16 TB respectively.
  20. ^ The Mac OS provides two sets of functions to retrieve file names from an HFS Plus volume, one of them returning the full Unicode names, the other shortened names fitting in the older 31 byte limit to accommodate older applications.
  21. ^ HFS Plus mandates support for an escape sequence to allow arbitrary Unicode. Users of older software might see the escape sequences instead of the desired characters.

  25. ^ a b Depends on kernel version and arch. For 2.4 kernels the max is 2 TB. For 32-bit 2.6 kernels it is 16 TB. For 64-bit 2.6 kernels it is 8 EB.
  26. ^ ReiserFS has a theoretical maximum file size of 1 EB, but "page cache limits this to 8TB on architectures with 32 bit int"[3]
  27. ^ Note that the filename can be much longer XFS#Extended_attributes
  28. ^ a b XFS has a limitation under Linux 2.4 of 64 TB file size, but Linux 2.4 only supports a maximum block size of 2 TB. This limitation is not present under IRIX.
  29. ^ a b QFS allows files to exceed the size of disk when used with its integrated HSM, as only part of the file need reside on disk at any one time.
  30. ^ Varies wildly according to block size and fragmentation of block allocation groups.
  31. ^ Maximum combined filename/filetype length is 236 bytes; each component has an individual maximum length of 255 bytes.
  32. ^ Maximum pathname length is 4,096 bytes, but quoted limits on individual components add up to 1,664 bytes.
  33. ^ This restriction might be lifted in newer versions.
  34. ^ a b Maximum file size on a VMFS volume depends on the block size for that VMFS volume. The figures here are obtained by using the maximum block size.

  38. ^ Joliet Specification
  39. ^ [4]
  40. ^ a b c Some FAT implementations, such as in Linux, show file modification timestamp (mtime) in the metadata change timestamp (ctime) field. This timestamp is however, not updated on file metadata change.
  41. ^ a b Particular Installable File System drivers and operating systems may not support extended attributes on FAT12 and FAT16. The OS/2 and Windows NT filesystem drivers for FAT12 and FAT16 support extended attributes (using a "EA DATA. SF" pseudo-file to reserve the clusters allocated to them). Other filesystem drivers for other operating systems do not.
  42. ^ The f-node contains a field for a user identifier. This is not used except by OS/2 Warp Server, however.
  43. ^ NTFS access control lists can express any access policy possible using simple POSIX file permissions (and far more), but use of a POSIX-like interface is not supported without an add-on such as Services for UNIX or Cygwin.
  44. ^ As of Vista, NTFS has support for Mandatory Labels, which are used to enforce Mandatory Integrity Control. See [5]
  45. ^ As of 10.5 Leopard, Mac OS X has support for Mandatory Labels. See
  46. ^ a b c d Access-control lists and MAC labels are layered on top of extended attributes.
  47. ^ Some operating systems implemented extended attributes as a layer over UFS1 with a parallel backing file (e.g., FreeBSD 4.x).
  48. ^ a b c d e f g h i Some Installable File System drivers and operating systems may not support extended attributes, access control lists or security labels on these filesystems. Linux kernels prior to 2.6.x may either be missing support for these altogether or require a patch.
  49. ^ ext4 has group descriptor and journal checksums only
  50. ^ Creation time is stored in the backing ext4 filesystem, but is not yet sent to clients.
  51. ^ Lustre has checksums for data over the network, but depends on backing filesystem and hardware for checksums of persistent data
  52. ^ a b c d e f Not available with ext3/4, but will be available with ZFS OST/MDT backing filesystems.
  53. ^ ocfs2 computes and validates checksums of metadata objects like inodes and directories. It also stores an error correction code capable to fixing single-bite errors.
  54. ^ a b CRCs are employed for certain types of metadata.
  55. ^ Record Management Services (RMS) attributes include record type and size, among many others.
  56. ^ File permission in 9P are a variation of the traditional Unix permissions with some minor changes, eg. the suid bit is replaced by a new 'exclusive access' bit.
  57. ^ MAC/Sensitivity labels are per filesystem. A label per file are not out of the question as a future compatible change but aren't part of any available version of ZFS.
  58. ^ Solaris "extended attributes" are really full-blown alternate data streams, in both the Solaris UFS and ZFS. ZFS also has "system attributes" used for storing MS-DOS/NTFS compatible attributes for use by CIFS; as well as some attributes ported from FreeBSD
  59. ^ a b Time the file was recorded on the volume always available; "File Creation Date and Time" available only if the file has an Extended Attribute block.
  60. ^ a b Not applicable to file systems on a read-only medium.
  61. ^ a b Available only if the file has an Extended Attribute block.
  62. ^ Symlinks only visible to NFS clients. References and Off-Disk Pointers (ODPs) provide local equivalent.
  63. ^ System V Release 4, and some other Unix systems, retrofitted symbolic links to their versions of the Version 7 Unix file system, although the original version didn't support them.
  64. ^ a b c "6", Parted manual, GNU.
  65. ^ Context based symlinks were supported in GFS, GFS2 only supports standard symlinks since the bind mount feature of the Linux VFS has made context based symlinks obsolete
  66. ^ Optional journaling of data
  67. ^ As of Windows Vista, NTFS fully supports soft links. See this Microsoft article on Vista kernel improvements. NTFS 5.0 (Windows 2000) and higher can create junctions, which allow any valid local directory (but not individual files) ("target" of junction) to be mapped to an NTFS version thereof ("source" = location of junction). The source directory must lie on an NTFS 5+ partition, but the target directory can lie on any valid local partition and needn't be NTFS. Junctions are implemented through reparse points, which allow the normal process of filename resolution to be extended in a flexible manner.
  68. ^ a b NTFS stores everything, even the file data, as meta-data, so its log is closer to block journaling.
  69. ^ While NTFS itself supports case sensitivity, the Win32 environment subsystem cannot create files whose names differ only by case for compatibility reasons. When a file is opened for writing, if there is any existing file whose name is a case-insensitive match for the new file, the existing file is truncated and opened for writing instead of a new file with a different name being created. Other subsystems like e. g. Services for Unix, that operate directly above the kernel and not on top of Win32 can have case-sensitivity.
  70. ^ NTFS does not internally support snapshots, but in conjunction with the Volume Shadow Copy Service can maintain persistent block differential volume snapshots.
  71. ^ http://www.bleepingcomputer.com/tutorials/tutorial133.html
  72. ^ Mac OS System 7 introduced the 'alias', analogous to the POSIX symbolic link but with some notable differences. Not only could they cross file systems but they could point to entirely different file servers, and recorded enough information to allow the remote file system to be mounted on demand. It had its own API that application software had to use to gain their benefits-- this is the opposite approach from POSIX which introduced specific APIs to avoid the symbolic link nature of the link. The Finder displayed their file names in an italic font (at least in Roman scripts), but otherwise they behaved identically to their referent.
  73. ^ Hard Links on HFS+
  74. ^ Metadata-only journaling was introduced in the Mac OS 10.2.2 HFS Plus driver; journaling is enabled by default on Mac OS 10.3 and later.
  75. ^ Although often believed to be case sensitive, HFS Plus normally is not. The typical default installation is case-preserving only. From Mac OS 10.3 on the command newfs_hfs -s will create a case-sensitive new file system. HFS Plus version 5 optionally supports case-sensitivity. However, since case-sensitivity is fundamentally different from case-insensitivity, a new signature was required so existing HFS Plus utilities would not see case-sensitivity as a file system error that needed to be corrected. Since the new signature is 'HX', it is often believed this is a new filesystem instead of a simply an upgraded version of HFS Plus. See Apple's File System Comparisons (which hasn't been updated to discuss HFSX) and Technical Note TN1150: HFS Plus Volume Format (which provides a very technical overview of HFS Plus and HFSX).
  76. ^ Mac OS Tiger (10.4) and late versions of Panther (10.3) provide file change logging (it's a feature of the file system software, not of the volume format, actually). See fslogger.
  77. ^ HFS+ does not actually encrypt files: to implement FileVault, OS X creates an HFS+ filesystem in a sparse, encrypted disk image that is automatically mounted over the home directory when the user logs in.
