IFO file is a DVD Information file that stores information about Chapters, Subtitles, and Audio Tracks.
IFO information is a video title set (VTS). When the disc is accessed with a DVD-ROM, at least two directories are present: AUDIO_TS (audio title set) and VIDEO_TS (video title set). An IFO file is one of three types of files that are used on DVDs. It contains important navigational information, such as where a video chapter begins, and where audio and subtitle streams exist within the movie (VOB) file. IFO files are not encrypted.
The IFO file is a file on a DVD (Digital Video Disk) that contains information used by your DVD player to allow it to play the disk. It contains information like start-up options, titles, chapter divisions and audio location. IFO files are in a computer language called "binary" and can be opened by notepad or another word processor, but the information shows up as random characters and you cannot see what is actually in the file. To see the IFO file properly, you must use a special program to open them. One of the best IFO viewing and editing programs is called IfoEdit, which you can download and use for free.
Download IfoEdit and save it to your desktop.
Right-click on the compressed file and select Extract All...; click Next, then Next.
Make sure Show extracted files is checked on the next screen and click Finish.
Open IfoEdit by double-clicking on it. If you get an Open File -- Security Warning box, just click Run and IfoEdit will open.
Place a DVD in your computer DVD Drive, and in the lower left-hand corner of IfoEdit, click Open.
Navigate to your DVD drive and double-click on the Video folder. There you will see the IFO files.
Select the one you wish to open and click Open.
Here's a detailed example of how to create valid IFO files for the movie 'Final Fantasy disc1'. You can see the usage only from the first VOB file. Other files are just the same. You will need to download IfoEdit.
Below you can see our VOB file. It's just one:
Start IfoEdit, and press the button Create IFOs:
You will be prompted for the VOB file, you want to create the IFO files for. So specify our VOB file:
Now you will be prompted for a destination directory for the output IFO files. Take the same directory, and just press Save:
IfoEdit now scans the VOB file and collects all IFO-releated information:
After it has finished collecting all needed information from the VOB files, it creates two new IFO files:
Now you need to do some little modifications. Click on VTS_01_0.IFO, and you will notice that the audio and subpicture attributes are not correct:
The channels of the AC-3 audio streams are all set to 1ch. You need to edit this. Go into the table VTSI_MAT and scroll down to the audio VTSTT attributes:
The Audio stream 1 and 2 have 6 channels, and the other have 2 channels. Double click the Aud_1 attributes and change the second hex-value to 05:
Repeat the same for the second audio attribute. For the 3.rd, 4.th and 5.th, we will put the value 01 in there:
If you now go back to the VTS_Overview, you will see our audio attributes are now correct:
Save now your IFO file, and enjoy your movie.
