The invention discloses a quick transmitting method of data files of a campus network based on data grids. By adding interference mechanism to the FTP system which is widely used in common campus networks, a transition to a data grid environment can be performed quickly, files can be transmitted quickly by using the advantages of the data grids. Sources of the original FTP system can be imported into the new data grid environment automatically by the running of a system discovering module, a source discovering module, a function discovering module, a conversion module, a request response converting module and the like, and at the same time, existing data transmission software is compatible in the running process of data grids, therefore, the data grid using barrier is reduced, and disadvantages that the data grid has a long period of application development, is hard to combine with existing sources, is difficult for users to master, and the like are overcome.
