Do you think that Peer-to-Peer, FTP, IRC technologies etc…make you use your brain too much? There is a simpler technology to use, Autosend. This software allows file-sharing by only using your e-mail account. You simply specify the directory which contains the files that you would like to share and the solicited file extensions. You can at the same time limit the transfers to prevent any saturation of the band-width. Besides the fact that it is paying, the other inconvenient of this software is that it is only practical when you would like to share a great number of small size files.
