iHPFS (ver 1.28) Abandoned Freeware It would not be uncommon to find DOS readable documents on a HPFS (OS/2) hard drive. iHPFS allows DOS to access a HPFS drive, including viewing the long file names. Your HPFS drive appears as a normal DOS drive, except that it cannot be written to (it essentially appears to DOS as if it was a CD-ROM drive). NOTE: ihpfs.asm is the source code.
