Hi there, I'm new to this forum so please forgive me if I have missed this info somewhere. I have been trying to read through the past forums, but so far I haven't ran across this information. What program do you all use to zip your files for posting to a download site or for combining a kit to sell on a site such as Etsy? I have read of some that are supposedly free on the internet, but don't know anything about them. Would also love to hear about any good free ones you all may have used. Thanks in advance.
