DivX is a brand name of products created by DivX, Inc. (formerly DivXNetworks, Inc.), including the DivX Codec which has become popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality. The DivX codec uses lossy MPEG-4 Part 2 compression, also known as MPEG-4 ASP, where quality is balanced against file size for utility .
Probably the most well known and well used format for video files stored on PCs, DivX is used due to its great video quality compared to the small file sizes it creates from video (you can fit a 1 hour 40 minute feature film onto a single CD, 700MBs, in very good quality). DivX uses MPEG-4 compression to create a file in an AVI container, resulting in the file ending in .avi.
DivX is widely supported by many standalone DVD players and PCs. In recent times, open source codecs such as Xvid have provided a good alternative to DivX files. Generally, if you want to store your files on your PC then either DivX or Xvid should be your main choice.
