Have you ever tried to watch a video file only to find out your usual media player program can't play it? QuickTime and Windows Media Player come preloaded on most computers, but they don't play every file type. VLC is a free, open-source media player that plays almost every audio and video file format in existence, plus CDs, DVDs and Blu-ray. It even handles webcams and streaming content, and it can convert media from one format to another.Not only is it powerful, it's lightweight. There isn’t an overabundance of flashy features and useless add-ons. That means it runs fast. Plus there are no ads!
