Abstract
A partial file stream is utilized to conserve resources and provide services when a file stream such as video file stream is requested for processing to generate a thumbnail. A file stream host provides a partial file stream generated from the beginning and end parts of the video file stream adjoined by a middle part. The partial file stream minimizes resource utilization. The partial file stream also enables access by external processes to generate the thumbnail and minimize exposure to security risks by stopping direct access to the file stream host.
