DescriptionMedia Center 27.0.66 adds the ability to share a file to a friend from your library, over your network or the Internet, by sending a link via text or email..
Files will be shared using a secret encryption key so there is no way to guess what a URL will be.
InstructionsTo share a file, right-click the file and pick Library Tools > Share. You can also add a Share toolbar button to the top or bottom toolbar by right clicking on it.
You will be given an option of whether to place the local or internet URL on the clipboard.
Media Network must be checked in MC's settings and your outside address at the port Media Center is running Media Network on will need to be reachable. Set up port forwarding for port 52199 on your router. Forward inbound access to your computer's IP address.
A field "Shared" will be checked for the shared files. If you uncheck the field, it will no longer be accessible.
If you want to invalidate all your shares, you can choose Options > Media Network > Advanced > Reset sharing key (makes all shares invalid)...
