HPFS

HPFS, which stands for High Performance File System, was a file system developed by Microsoft for its OS/2 operating system. It was introduced in 1988 with the release of OS/2 version 1.2. HPFS was designed to be a more robust and efficient file system than the FAT (File Allocation Table) file system used in MS-DOS. Key features of HPFS included support for larger disk drives, longer file names, and improved performance. It utilized a tree-like structure for directory organization, which allowed for faster file searching compared to the flat structure of FAT. HPFS also incorporated features like file system journaling to enhance data integrity and reduce the risk of corruption in case of system crashes. While it offered significant improvements over FAT, HPFS never gained widespread adoption outside of OS/2. Microsoft later developed NTFS (New Technology File System) for Windows NT, which became its primary file system. HPFS was eventually discontinued.
