Hi Gurus, I have a query, what will happen if I add another chunk (cooked file) and the offset is not zero. Regards. Jojo

Not using Informix offsets you can't. You will have to partition the drive at the OS level or using a Volume Manager to create two 2GB logical devices. You can then use these as your chunks. Art S.
