Bruce, I am most familiar with the dos version of pkzip, which gives you all the instructions if you try to run the program without any arguments.(very handy - doucmentation built into the program!) I know that they have touted later versions as having long name support, so that wouldn't be a problem. zipping multiple files into one isn't hard. you do a multiple selection under windows, or use a wildcard name under dos and "add" to the zipfile. I imagine you could set an HTML link to unzip, play and delete a file. PKWARE has a site on the web
