A method of accessing digital rights management (DRM) files and non-DRM files in a mobile device includes providing an intermediate interface between one or more application modules of the mobile device and a file system of the mobile device, and providing a DRM module between the intermediate interface and the file system. The method further includes determining if the file is controlled by DRM through the intermediate interface when a selected application module sends a file request to the file system to access the file, processing the file request using the DRM module to verify if the file is controlled by DRM, and returning a processed result to the selected application module.
