Editing High Performance File System (section)

== Native support under Windows ==
[[Windows 95]] and its successors [[Windows 98]] and [[Windows Me]] have no support for HPFS. {{citation needed span|date=May 2023|They listed the [[NTFS]] partitions of networked computers as "HPFS"}}, because NTFS and HPFS share the same [[Partition type|filesystem identification number]] in the partition table.

[[Windows NT 3.1]] and [[Windows NT 3.5|3.5]] have native read/write support for local disks and can even be installed onto an HPFS partition. 

[[Windows NT 3.51]] can also read and write from local HPFS formatted drives. Starting with [[Windows NT 4]] the filesystem driver ''PINBALL.SYS'' enabling the read/write access is not shipped anymore. Later Windows versions do not ship with this driver. Note that this driver is limited to 4GB HPFS volumes.

Microsoft retained rights to OS/2 technologies, including the HPFS filesystem, after they ceased collaboration with IBM. 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. However, since HPFS lacks a [[Journaling file system|journal]], any recovery after an unexpected shutdown or other error state takes progressively longer as the filesystem grows. A utility such as [[CHKDSK]] would need to scan each entry in the filesystem to ensure no errors are present, a problem which is vastly reduced on NTFS, which simply replays the journal.
