Hello all. I am running Ruby 1.8.2 on XP professional. Have installed RubyZip through gems. I have tried to create a zip file containing all of the .dat file in a particular directory. It appears that I only get the last .dat file ziped. Can anyone point me in the right direction. Please remember I have just started to learn Ruby but am trying to create some small but usefull functions. I looked through the news group for similar post and tried googling for additional documentation on the RubyZip and seem to have come up short. Len Sumnler
