high performance file system. A file system available in OS/2 and WIN NT that supports long, mixed-case file names up to 256 characters, up to 64K of extended attributes per file, faster disk access with an advanced disk cache for caching files and directory information, highly contiguous file allocation that eliminates file fragmentation, and support for hard disks up to 64GB in size. DOS does not recognize the HPFS file structure. HPFS cannot be used on a floppy disk.

high performance file system. The file system designed for the OS/2 version 1.2 operating system.
High-performance file system (HPFS); primarily used with the OS/2 operating system version 1.2 or later. It supports long filenames but does not provide security.
See high-performance file system.
An OS/2 file system that has faster input/output than the file allocation table file system; it does not restrict file naming to eight characters with a three character extension; and is compatible with the FAT file system.
High Performance File System. An OS/2 file system that allows long file names.
High Performance File System. An OS/2 file system that offers multiple improvements over FAT, which OS/2 also supports, at the expense of compatibility with PC-DOS or Windows. No other operating system can read an HPFS-format disk partition, so neither dual boot or partition sharing is not possible (except between two OS/2 systems). HPFS offers greater reliability, 2 to 10 times performance improvement and support for larger files. HPFS is compatible with FAT at the API level. cf. NTFS.
