[Zope] zexp file

Is there any way to extract files from a .zexp file? I have an exported file from a way older Zope server that I can't get to import into our current Zope server. I'm sure it's because it used some product that I don't currently have installed, but I can't figure out what it is. There are some JPGs in that zexp that I need to get out. Can this be done? Thanks, Rick
