A network file transfer and caching system is presented. The system provides multiple access utilities to select and transfer files to other users. The system is of particular use where the size of the files precludes transfer by other means such as e-mail attachments. The system is uniquely integrated into the operating systems by providing right click context menu file selection and process initiation. New utilities enable improved workflow by providing download information without the need to wait for completion of the network transfer process. Network transfer processes may progress in the background without user oversight or intervention. Files are cached and securely available to selected receivers of the files. The caching process may be managed by selected parameters related to number of downloads and time limits for availability of downloads.
