Abstract
A method for sharing a data file among devices is provided, wherein the data file corresponding to a first data file stored in any of information-processing devices is transmitted to a file server, when a mobile terminal controlling a data-file-sharing operation requests registration of the first data file, as an object to be used by the other device. The data file is stored in a management region. The file server transmits file-sharing information including location information and attribute information of the data file. The file-sharing information is transmitted from the information-processing device to the mobile terminal which selects a second data file for reception on the basis of the attribute information, accesses the file server on the basis of the location information corresponding to the second data file, and requests transmission of the second data file so that the second data file is transmitted.
