It aims at supporting different computer operating systems such as Windows, classic Mac OS, and Unix like systems, so that data may be exchanged. HistoryeditISO 9. High Sierra Format file system. High Sierra arranged file information in a dense, sequential layout to minimize nonsequential access by using a hierarchical eight levels of directories deep tree file system arrangement, similar to UNIX and FAT. To facilitate cross platform compatibility, it defined a minimal set of common file attributes directory or ordinary file and time of recording and name attributes name, extension, and version, and used a separate system use area where future optional extensions for each file may be specified.

ISO, where it was eventually accepted as ISO 9. In 2. 01. 3, ISO published Amendment 1 to the ISO 9. ISO 9. 66. 0 and widely used Joliet Specification. SpecificationseditOverall structureeditThe following is the rough overall structure of the ISO 9. ISO 9. 66. 0 File System. System Area 3. 2,7. BUnused by ISO 9. Data Area. Volume Descriptor Set. Path tables, Directories and Files. The System Area, the first 3. ISO 9. 66. 0 and therefore available for other uses. For example, a CD ROM may contain an alternative file system descriptor in this area, as it is often used by hybrid CDs to offer classic Mac OS specific and mac. OS specific content. All multi byte values are stored twice, in little endian and big endian format, either one after another in what the specification calls both byte orders, or in duplicated data structures such as the path table. As the structures have been designed with unaligned members, this both endian encoding does however not help implementors as the data structures need to be read byte wise to convert them to properly aligned data. Volume descriptor seteditThe data area begins with a set of one or more volume descriptors, terminated with a volume descriptor set terminator. Collectively the volume descriptor set acts as a header for the data area, describing its content similar to the BIOS parameter block used by FAT, HPFS and NTFS formatted disks. Volume Descriptor Set. Volume Descriptor 1. Volume Descriptor NVolume Descriptor Set Terminator. The volume descriptor set terminator is simply a particular type of volume descriptor with the purpose of marking the end of this set of structures. Volume descriptoreditEach volume descriptor is 2. Mode 1 or Mode 2 Form 1 sector. They have the following structure 2,0. Parts. Type. Identifier always CD0. Version always 0x. Data. Sizes. 1 byte. The data field of a volume descriptor may be subdivided into several fields, with the exact content depending on the type. Standard volume descriptor types are the following Basic Volume Descriptor Types. Type field value. Type. 0Boot Record Volume Descriptor. Primary Volume Descriptor. Supplementary Volume Descriptor, or. Enhanced Volume Descriptor. Volume Partition Descriptor. Volume Descriptor Set Terminator. An ISO 9. 66. 0 compliant disk contains at least one Primary Volume Descriptor describing the file system and a Volume Descriptor Set Terminator for indicating the end of the descriptor sequence. The Primary Volume Descriptor provides information about the volume, characteristics and metadata, including a root directory record that indicates in which sector the root directory is located. Other fields contain the description or name of the volume, and information about who created it and with which application. The size of the logical blocks which the file system uses to segment the volume is also stored in a field inside the primary volume descriptor, as well as the amount of space occupied by the volume measured in number of logical blocks. In addition to the Primary Volume Descriptors, Supplementary Volume Descriptors or Enhanced Volume Descriptors may be present. Supplementary Volume Descriptors describe the same volume as the Primary Volume Descriptor does, and are normally used for providing additional code page support when the standard code tables are insufficient. The standard specifies that ISO 2. ISO 2. 37. 5 escape sequences are used to identify each particular code page used. Consequently, ISO 9. However, ISO 9. 66. Enhanced Volume Descriptors were introduced in ISO 9. Amendment 1. They relax some of the requirements of the other volume descriptors and the directory records referenced by them for example, the directory depth can exceed eight, file identifiers need not contain. Redundant copies of each volume descriptor can also be included in case the first copy of the descriptor becomes corrupt. Directories and filesedit. Overview of the ISO 9. Directory entries are stored following the location of the root directory entry, where evaluation of filenames is begun. Both directories and files are stored as extents, which are sequential series of sectors. Files and directories are differentiated only by a file attribute that indicates its nature similar to Unix. The attributes of a file are stored in the directory entry that describes the file, and optionally in the extended attribute record. To locate a file, the directory names in the files path can be checked sequentially, going to the location of each directory to obtain the location of the subsequent subdirectory. However, a file can also be located through the path table provided by the file system. This path table stores information about each directory, its parent and its location on disk. Since the path table is stored in a contiguous region, it can be searched much faster than jumping to the particular locations of each directory in the files path, thus reducing seek time. The standard specifies three nested levels of interchange paraphrased from section 1. Level 1 File names are limited to eight characters with a three character extension. Directory names are limited to eight characters. Files may contain one single file section. Level 2 Files may contain one single file section. Level 3 No additional restrictions than those stipulated in the main body of the standard. That is, directory identifiers may not exceed 3. Files are also allowed to consist of multiple non contiguous sections with some restrictions as to order.
