The invention discloses a
resource file updating method, device and
system and a
server, and belongs to the technical field of computers. The method comprises the steps of sending a request message to the
server, wherein the request message comprises the name and the identification of a
resource file, and the identification is acquired according to the name of the
resource file and available data of the resource file; receiving latest data which correspond to the name of the resource file and are fed back according to the name and the identification of the resource file by the
server, and replacing the available data of the resource file through the latest data of the resource file. According to the resource file updating method, device and
system and the server, whether the resource file is updated or not is judged by comparing data corresponding to the resource file on a mobile terminal and the server, if updating exists, the latest data of the resource file are acquired, so that automatic updating of the resource file is achieved, the fact that an entire installing
package is downloaded again under the condition that certain resource files are updated is avoided, and the downloading burden of the mobile terminal is lowered.
