What Does High-Performance File System (HPFS) Mean?
The high-performance file system (HPFS) is a file system designed especially for the IBM OS/2. It is known for handling large files of up to 2 GB across multiple hard disks, as well as for handling long file names of up to 256 bytes. HPFS was designed to improve on the weaknesses of the file allocation table file system.
Techopedia Explains High-Performance File System (HPFS)
The advantages of HPFS include:
Contiguous storage Separate date stamps for file creation and last access and modification Less file fragmentation Smaller cluster size Support for storage devices of up to 512 GB Faster disk operation and file access of the root directory at the midpoint of the disk rather than the beginning
Requires more system memory Requires disk partitions not recognized by MS-DOS, which prevents a computer from booting from a floppy disk Requires a special utility (Partition Magic from PowerQuest) to access the HPFS partition
