Let me just start off by saying, I do not support filesharing of illegal files in any way. Now that that's out of the way ;)
Limewire is a gnutella client which is open standard, and allows you to share all sorts of fun files, including the all popular MP3. Limewire can really be a piece of garbage and overwhelming at times.
Acquisition is a gnutella client that uses code from limewire. It features all sorts of features like ultrapeers, multi-source downloads, and boasts a very nice user interface. It is essentially Limewire that looks and works better. Overall it is a very nice application that looks good and is easy to use.
iSwipe is program that searches FTP, hotline, Napster, OpenNap, and Carracho servers. The idea is phenomenal. The program isn't ;) It can sometimes work, but this is rare, in my experiences.
BitTorrent is based on an amazing idea....Upload as you download ;) BitTorrent has no built in search feature, or no special features...All it does is take a 128KB file that you can download from searching a website, and downloads it. It uploads what's already been downloaded at the same time. You never know who you're downloading/uploading to/from. I use this all the time for stuff like legal Pearl Jam concerts. Only problem with this program is, finding the websites to download the little 128KB file from...This involves a lot of googling, and sites that offer the little 128KB files frequently get shut down ;) I would definitely not recommend this program to the computer newbie ;)
No, its not the Nextel thing. This is filesharing ;). "Unlike other impersonal, server-driven file-sharing networks, Direct Connect offers a community-oriented, open, user-controlled network. Moreover, Direct Connect's network architecture is built on a peer-to-peer foundation; users run, control, and maintain the network. Users are able to share any type of file - absolutely no restrictions. These files are easily viewed through a familiar organized windows-explorer interface. To conveniently access the plethora of files, advanced searching capabilities and filters are provided. All of these features are integrated into Direct Connect's unique communal file-sharing system." In the end, you can get a lot of awesome stuff off of Direct Connect, but it may sometimes require a lot of patience ;)
Just another filesharing application ;) Personally, I hate this program, and I would be careful using it as people like the MPAA and RIAA are looking for people a lot through this protocol....
While this is still in beta, this is my favorite Filesharing app :) It does Gnutella, OpenFT, and the all popular Fasttrack networks (Kazaa). It may be very buggy, but it works the best and will bring up exactly what you're looking for.
HotFries ' favorite!
Poisoned is probably my favorite program, followed by BitTorrent, Acquisiton, and DirectConnect. But remember people, there's ALWAYS NEWSGROUPS! ;)
