NATFILE is an uploading application tool. The tool is used to transfer files from a personal computer and send it directly to an internet server. The application tool also can be used to transmit files directly to other computers and even perform the file copying task. The tool has an intelligent code that is used to establish contact between two computers that are operating on the same network servers. If at all the two computers are running on the same network configuration, files are sent directly without having to apply any transfer medium. This application is largely important to people who like sharing files while at the same time they want to avoid the numerous procedural steps.
