LIBOX is a free service that lets you share and sync your media anywhere on any device. The service is totally free and will never limit how much media you can add or how many people you can share it with. It automatically syncs your media collection across your computers and streams it to any browser or mobile device so it is available anywhere you want it and it keeps your media in its original format and quality so you and your friends do not have to worry about weird formats and converting them.
