FrostWire is an open source Peer to Peer (P2P) application based on the Gnutella network and a popular alternative to the now defunct Limewire.

In fact, FrostWire has more than just a few similarities to Limewire although unlike the latter, it does not carry advertising and there are no annoying pop ups. Just as Limewire was, FrostWire is straightforward and easy to use. A simple search bar, divided by category, makes it a breeze to browse for a file, whether it is a video, image, audio, or program. FrostWire also has a What’s New button to check out what popular files users have recently exchanged.

One particularly handy feature of FrostWire is a special direct connect option. If you know the IP address of one of your friends, type it in the box and FrostWire will browse to that user’s files. This is a quick way of sharing files with someone you know although it would be even better if you could enter the username of a user rather than the IP address.

In terms of speed, much will depend on the speed of your own connection. It definitely helps though if you've correctly opened your router’s ports and whether you’re downloading a popular file or not. To avoid the risk of downloading copyrighted or adult material, FrostWire also allows you to apply content filters. Another handy feature of FrostWire is a built-in media player. Video and audio can be tested using Frostwire’s media player which gives you an immediate preview of your file.

However, one major annoyance with Frostwire is the number of fake files on it. Many songs and files look genuine but are in fact either completely fake or in the worst case scenarios, malicious. You should be very careful when opening files. It should also be noted that FrostWire is basically a stripped-down version of Limewire, but is a not-for-profit project. The developers claim it will never support Digital Rights Management (DRM) or any type of advertising. However, the demise of Limewire due to legal issues mean that FrostWire may well be targeted in the future for closure.

FrostWire for Mac is a hugely popular alternative for anyone who misses Limewire but there are a lot of fake files and it doesn't quite measure up to the latter in most areas.
