High-Performance File System

   Abbreviated HPFS. A file system available in OS/2 and Microsoft Windows NT that supports the following:
   • Long, mixed-case filenames of up to 255 characters
   • As much as 64KB 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
   • Hard disks of up to 64GB in size MS-DOS does not recognize the HPFS file structure, it cannot be used on a floppy disk, and it is not supported in Windows NT 4 or later.
