how to download torrent files..

First thing we need to know is what a torrent file is..
Torrent can be just any type of file, such as movie, song, game, or application. It is a file sent via the BitTorrent protocol. Take note that torrent files are different from regular downloads in that they are usually downloaded from more than one server at a time. The BitTorrent protocol uses multiple computers to transfer a single file. For example, if a user begins downloading a movie file, the BitTorrent system will locate multiple computers with the same file and begin downloading the file from several computers at once.

How to download torrent file?
In order to download a torrent file, you will need a BitTorrent client, which is a software that serves as a download manager for torrent files. There are many BitTorrent client you can choose from and here are some of them.., (BitComet, uTorrent, Azureus, BitTornado, Shareaza.., etc.)

How to choose the right BitTorrent client for you to use?
For me, I uses BitComet, simply because it serves me right in terms of the speed of my downloads. Remember, the speed of your downloads also depends on the bandwidth your ISP (Internet Service Provider) has to offer, so only choose the BitTorrent client that can maximize your bandwidth.

Where to download torrent files?
You can download them at torrent sites such as btjunkie, ISOHUNT, mininova, bitdig, etc., or you can simply go to Torrent Finder (a BitTorrent Multi Search Engine which searches 158 torrent sites and trackers from one page).

I recommend..
For movie downloads, I recommend searching in MComet.com, it got all the info (cast, genre, plot-outline) of the movie you want to download. MComet is associated with wTorrent (a torrent site) where you can download the torrent file of the movie. In wTorrent, you can view the screenshots of the movie to see whether the copy is good/bad before downloading it.
