Plex is everywhere: You need a Plex app on both ends of your stream, so it needs to be available on a variety of platforms for everything to go smoothly. You can also create and manually add other folders, and Plex will add integrate that media and track those folders for future changes.

Or you can subscribe to the Plex Pass, which adds features such as DVR recording, syncing files to mobile devices, and coordinating with cloud storage services to stream media from the cloud to your device.

The base product is available for free on Windows without ads. Plex is media-playing software that can stream a file from one device to another over your local network.
