The problem is one of memory, your version of AHDI doesn't allocate enough memory for more than twenty subdirectories. A new version of AHDI has been available for a few months that solves this problem, contact ATARI-UK for a copy. If they don't have it, its available on the ATARIDEV section of compuserve, but you need to be an authorized developer to download it This should do it Neal 'NAK' Katz #include > > Nigel Roles > Department of Computer Science > University of York > > ..!ukc!minster!nigel
