Abstract: As the diversity of document type causes that systems cannot ensure all of files display normally, file format transform plays a pivotal role in resolution of this problem. However, the concurrent document type transfer function is universally a part of the system as a sub-module, which makes different systems need to develop document type transfer module repeatedly. In this paper, document type transfer component based on Web service is proposed, which enhances the reusability of the component. Moreover, aiming at the multi-core hardware system of computer, concurrent mechanism and command pattern design are given to manage the transfer task in a unified method, which promotes the efficient and throughput of transfer component. The test of deployment illustrates that not only the component can ensure the transform of almost all of video file and part of text file, but also the concurrent design runs normally and improves the efficient of file transform actually.
