Yo, I'm the Anonymous user that posted earlier. I wanted to let you know I stumbled upon another post you commented on that explained it. Incase you missed it, you can view that post @ http://cameyo.activeboard.com/t61484046/upload-large-package-with-exe-and-dat-via-online-portal/
To add some contexts, this is meant for hosting your own apps on your private cameyo server. By storing an app on the private cameyo server, the server doesn't have to download it each time a user launches it. The result is the app loading much faster online since the server doesnt have to download it and instead rely on a copy locally on the server.
