Brian, the easiest way to transfer files two and from the tablet is with a memory card and memory card reader. It doesn't matter where you put them, if you are using kagu or ukmp, they will probably be found automatically. Use the file manager on the nokia to locate the file and then tap on it to play it in the media player.

If you don't have a media card reader, there are other ways to connect. It is possible that you will already be able to see your other computers from the nokia file manager, then you can just copy files wirelessly. If not, you can map them with samba protocol. If your computer has bluetooth, you can connect with that. The USB cable which came with your nokia can be used to mount the nokia as a removeable drive.

Bit torrent is a p2p sharing protocol where files are split up and distributed amongst users who seed and leech from eachother. It is great because it reduces bandwidth loads on a single server.

To use, you will have to find a torrent file then load that in the bit torrent program and that will connect you to seeders. As you download the file, others will connect to you and download the parts you have already gotten.
