IFO DVD Format

In video editing, IFO normally refers to a file on DVD-Video disc and stands for InFOrmation.
IFO (Information) files contain an index of important information (such as timing information for search and seek functions) about the VOB (Video Object) files, which themselves contain the Video Data. The maximum size of a VOB file is 1GB; therefore the total data on the DVD is broken up into multiple VOB files. VIDEO_TS.IFO is a special master IFO file that contains information on all of the other IFO files on the media. In order for a DVD title to support both computer and consumer platforms, the program must contain a VIDEO_TS directory, with a VIDEO_TS.IFO file containing all information required for DVD playback.
IFO files provide information for DVD player where DVD-Video disc's chapters start, where certain audio tracks are located, etc.
