HPFS Is No Longer Supported on Windows 10

HPFS stands for High Performance File System and was a file system developed by IBM for OS/2. However, on Windows NT 4.0 and up to later versions of Windows 10, HPFS is no longer supported. File systems available for Windows 10 are FAT, FAT32, NTFS, and exFAT. Windows 10 can be installed to a partition ONLY if it uses NTFS.
