Macintosh File System (MFS) is a volume format (or disk file system) created by Apple Computer for storing files on 400K floppy disks. MFS was introduced with the original Apple Macintosh computer in January 1984.
HFS Plus is still supported by current versions of Mac OS, but starting with Mac OS X, an HFS volume cannot be used for booting, and beginning with Mac OS X 10.6 (Snow Leopard), HFS volumes are read-only and cannot be created or updated. In macOS Sierra (10.12), Apple's release notes state that "The HFS Standard filesystem is no longer supported."
The FAT file system is a file system used on MS-DOS and Windows 9x family of operating systems. [3] It continues to be used on mobile devices and embedded systems, and thus is a well-suited file system for data exchange between computers and devices of almost any type and age from 1981 through to the present.
In computing, a page fault is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space. Furthermore, the actual page contents may need to be loaded from a back-up, e.g. a disk.
HFSExplorer is a Java application for viewing and extracting files from an HFS+ volume (Mac OS Extended) or an HFSX volume (Mac OS Extended, Case-sensitive). The volume can be located either on a physical disk, in various Apple disk image and sparse disk image formats, or a raw file system dump. However, HFSExplorer is a read-only solution; it ...
Host computers running Linux are also able to read and write to a Mac's HFS or HFS+ formatted devices through Target Disk Mode. It is working out-of-the-box on most distributions as HFS+ support is part of the Linux kernel. However these filesystems cannot be checked for errors, so for shrinking or moving partitions it is preferred to use Mac OS.
Starting with Mac OS X Tiger, AppleDouble was used to store resource forks on file systems such as Windows SMB shares and FAT32 (File Allocation Table) volumes. In the HFS Plus file system, settings can be made to allow other forks in addition to the data and resource forks, to create a "multi-fork" application. [2]
This is the name given to the buffer where file contents (records) would be read into/written from. File access functions in DOS that used the FCB assumed a fixed location for the DTA, initially pointing to a part of the PSP (see next section); this location could be changed by calling a DOS function, with subsequent file accesses implicitly ...
