Hey Luc,

Thanks for your reply,

I was hoping that because the OVA format is a tar file that it would compress the data a bit. But I have found that using the defaults in ovftool the file size doesn't change any significant amount between the collection of files for ovf and the final ova file.

Either way it is much easier to deal with single ova files within the format of my PowerCLI script, so I will go with that.
