US 7,890,431 B2 · Trial access for media files from media list

Abstract

Embodiments of the present disclosure provide systems and methods for sharing media files. Briefly described, in architecture, one embodiment of the system, among others, can be implemented as follows. The system includes a file sharing application configured to initiate a communication session with a file server, where the file server manages download requests for media files listed on a dynamic list. Use of the media files is subject to a trial period that corresponds to a period that the media files remain on the dynamic list. The system further includes trial period checking logic configured to retrieve a new dynamic list and check whether a trial period for a media file has expired by determining whether the media file is listed on the new dynamic list and offer presentation logic configured to offer a user a license for continued use of a media file that has an expired trial period. Other systems and methods are also provided.
