HFS FILE SYSTEM MAXIMUM AMOUNT OF FILES WINDOWS
Since Windows NT 3.1 was designed for more rigorous (enterprise-class) use than previous versions of Windows, it included support for HPFS (and NTFS) giving it a larger storage capacity than the FAT12 and FAT16 filesystems. Microsoft retained rights to OS/2 technologies, including the HPFS filesystem, after they ceased collaboration with IBM.

Note that this driver is limited to 4GB HPFS volumes. Later Windows versions do not ship with this driver. Starting with Windows NT 4 the filesystem driver PINBALL.SYS enabling the read/write access is not shipped anymore. Windows NT 3.51 can also read and write from local HPFS formatted drives. Windows NT 3.1 and 3.5 have native read/write support for local disks and can even be installed onto an HPFS partition. They listed the NTFS partitions of networked computers as "HPFS", because NTFS and HPFS share the same filesystem identification number in the partition table. Windows 95 and its successors Windows 98 and Windows Me can read and write HPFS only when mapped via a network share they cannot read it from a local disk. Windows NT versions 3.51 (4.0) and earlier had native support for HPFS. This was a result of the Microsoft and IBM collaboration that gave both the right to use Windows and OS/2 technology.ĭue to the Microsoft dependence, limited partition size, file size limit of 2 GiB and the long disk-check times after a crash, IBM ported the journaling file system JFS to OS/2 as a substitute.ĭOS and Linux support HPFS via third-party drivers. Though IBM still had rights to HPFS, its agreement with Microsoft to continue licensing the HPFS386 version was contingent upon the company paying Microsoft a licensing fee for each copy sold. It is also highly tunable by experienced administrators. Thus, HPFS386 is faster than HPFS and highly optimized for server applications. HPFS386 is a ring 0 driver (allowing direct hardware access and direct interaction with the kernel) with built-in SMB networking properties that are usable by various server daemons, whereas HPFS is a ring 3 driver. HPFS386's cache is limited by the amount of available memory in OS/2's system memory arena and was implemented in 32-bit assembly language. HPFS386 provided with certain server versions of OS/2, or as added component for the server versions that did not come with it.The standard one with a cache limited to 2 MiB.

IBM offers two kinds of IFS drivers for this file system: HPFS also can keep 64 KiB of metadata (" extended attributes") per file. Root directory located at the midpoint, rather than at the beginning of the disk, for faster average access.Separate datestamps for last modification, last access, and creation (as opposed to last-modification-only datestamp in then-times implementations of FAT).An internal architecture that keeps related items close to each other on the disk volume.More efficient use of disk space (files are not stored using multiple-sector clusters but on a per-sector basis).Support for long file names (255 characters as opposed to FAT's 8.3 naming scheme).
