Windows only: Most people use torrent sites like Mininova or The Pirate Bay to search for torrents online, but free program TorrentFetcher lets you search straight from a desktop program and quickly start the transfer in your BitTorrent client of your choice.
Torrent sites offer a lot of information about the torrents they have available, but sometimes you just don't want to navigate to the site and look at all the annoying ads, or maybe you just want something a little simpler. TorrentFetcher is an easy solution, offering desktop search of btjunkie.org so you don't even have to open your browser.
While the program doesn't offer some of the really advanced information that websites might, it is a quick, easy alternative that does offer some advanced options. Like most torrent sites, you can search by the usual predetermined categories such as Music, Movies or Software and you can choose how many results show up in the window (up to 1000). It even has green and red colour-coding for good and bad quality torrents, respectively. There is also an option to decide whether you want them to automatically start after downloading — that way, all you have to do is search, double-click on the torrent you want and it will automatically open up in your default BitTorrent client.
TorrentFetcher is a free download, Windows only.
