KoolPlaya

KoolPlaya is a free multimedia player compatible with the majority of DirectShow codecs, with support for file formats including AVI, MPEG, WMV, MP3, DIVX, and XVID, just to name a few. The thing that really makes this program stand out is that it's as light as a feather. It needs no installation, so you can bring it with you on a USB drive or memory card. It has minimal load time and barely consumes any memory. But despite its small size, it has all the basic functions you'd expect in any multimedia player worth its salt: support for audio, video, playlists, zoom, fullscreen, loops, playing speed, etc. Other functions included in KoolPlaya allow you to bring the player into the foreground by default, an image capture tool, and the ability to adjust its interface to fit your needs.
