2000 zipPARTITONS

How do i partition a zip disk...250mb, i only use up about a quarter of the space on an individual disk and anything else after that it starts saying "too many files" and wont save anymore even though theres mad space left. whats up?

ha. .oh snap i was trying to change it on the''partition size" line instead of the 'parts' line . i remember reading it in the manual but i didnt get it at first thanks though peeeeeace
