Provided are computer-implemented methods and systems for performing media resource storage and management. The computer-implemented method and system implemented as a request manager is capable of monitoring requests for media resources in a content delivery network. For each monitored request, the request manager determines whether to generate a multifile for the requested media resource. For example, the request manager can first determine whether the media resource is eligible for multifile generation. If eligible, the request manager then determines whether the media resource has reached a popularity threshold. If the media resource has reached the popularity threshold, the request manager initiates generation of the multifile for the requested media resource. Generally, the generated multifile is stored in a storage system associated with the content delivery network.
