Abstract: A computer system and method for transferring a file from a device in proximity, including start downloading a file from a message addressed to a recipient, checking the message for one or more common recipients of the message; downloading the file from a remote server in response to no common recipient devices being in proximity to the recipient device, downloading the file from a remote server in response to the file not being available for transfer from any common recipient devices being in proximity to the recipient device, automatically applying file transfer permissions to the downloaded file for each of the common recipients of the message, checking if a common recipient device in proximity has requested to download the file, and transferring the file to the requesting common recipient device in proximity in response to the common recipient device in proximity being a mapped trusted device of the recipient device.
