Bakul, Thanks for the note. I=E2=80=99d not heard of =E2=80=9Cmakeit=E2=80=9D before, will go hunt = it down. 1. this was the 1980=E2=80=99s, space was always an issue :) 2. There are many cases where you=E2=80=99ve only got a=20 stream. This distributions were the first time I hit this problem type. 3. The distributions were a compressed tar or cpio of a directory structure, to be exploded at destination. There wasn=E2=80=99t a need to fit files onto media. cheers steve j -- Steve Jenkin, IT Systems and Design=20 0412 786 915 (+61 412 786 915) PO Box 38, Kippax ACT 2615, AUSTRALIA mailto:sjenkin@canb.auug.org.au http://members.tip.net.au/~sjenkin
