I updated my app yestoday. In this version, I add the copy/paste/email function in it. Air files have zip/unzip features, but I have not add zip/unzip button in toolbar. You can use a zip file as a folder in it, and if you select a folder to send to your friends, the folder will be automatically compressed as a zip file. I think I will add the zip/unzip button in next version if I have enough space in toolbar. This is my homepage: http://dreamo.jp/eng/airfiles/ You can find the video in it.
