A system and method is provided for downloading and uploading resource files, image files, and/or other files to and from a mobile phone using AT commands. An extended set of AT commands is defined for managing these files. The extended set of AT commands may then be used to directly download and upload files, or may be embodied in a software program for downloading and uploading files. The extended set of AT commands may also be used to manage and modify the resource files, image files, and other files, and to download, manage, and modify directories in the mobile phone.
