! Maximum filename length

! Allowable characters in directory entries


الرموز والحروف المسموح بها efn name note-25 These are the restrictions imposed by the on-disk directory entry structures th selves. Particular Installable File Syst drivers may place restrictions of their own on file and directory names and particular and operating syst s may also place restrictions of their own, across all filesyst s. MS-DOS, Microsoft Windows, and OS/2 disallow the characters / ? * > < and NUL in file and directory names across all filesyst s. Unix Unices and Linux disallow the characters / and NUL in file and directory names across all filesyst s.

! Maximum file size


اقصى حجم للملف


! Maximum volume size


اقصى حجم للقسم efn name note-4 For filesyst s 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 filesyst (e.g. 512 bytes and 128 kibibyte KiB for FAT — which is the cluster size range allowed by the on-disk data structures, although some Installable File Syst drivers and operating syst s do not support cluster sizes larger than 32 kibibyte KiB).

rh Version 6 Unix file syst (V6FS)




14 bytes efn name note-24 Depends on whether the FAT12, FAT16, and FAT32 < >impl entation has support for Long filename 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 filename 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 (replac ent 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 syst s (notably DOS and windows) effectively reserve th .




Any byte except Null character NUL and / efn name note-26 In these filesyst s 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 th are considered corrupt.




لا حدود محددة efn name note-12 The on-disk structures have no inherent limit. Particular Installable File Syst drivers and operating syst s 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. Linux has a pathname limit of 4,096.

255 bytes


Any byte except NUL efn name note-27 The . and .. directory entries in HPFS that are seen by applications programs are a partial fiction created by the Installable File Syst 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.

! NTFS


yes


yes efn As of Windows Vista, NTFS fully supports soft links.Windows Administration Inside the Windows Vista Kernel Part 1 NTFS 3.0 (Windows 2000) and higher can create < >junctions, which allow entire directories (but not individual files) to be mapped to elsewhere in the directory tree of the same partition (file syst ). These are impl ented through < >reparse points, which allow the normal process of filename resolution to be extended in a flexible manner.




no efn name note-37 NTFS stores everything, even the file data, as meta-data, so its log is closer to block journaling.


yes efn name note-37 (2000)


yes efn name note-36 While NTFS itself supports case sensitivity, the Win32 environment subsyst 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 subsyst s like e. g. Services for Unix, that operate directly above the kernel and not on top of Win32 can have case-sensitivity.

! HFS Plus


partial


yes


no


yes efn name note-48 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.


partial efn 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 syst .newfs_hfs(8) Mac OS X Manual Page 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 syst error that needed to be corrected. Since the new signature is "HX", it is often believed this is a new filesyst instead of a simply an upgraded version of HFS Plus. cite web publisher Apple url http //developer.apple.com/documentation/MacOSX/Conceptual/BPFileSyst /Articles/Comparisons.html File Syst Comparisons (hasn"t been updated to discuss HFSX) cite web publisher Apple url http //developer.apple.com/technotes/tn/tn1150.html Technical Note TN1150 HFS Plus Volume Format (Very technical overview of HFS Plus and HFSX.)
