How to Convert Video AVI to a UDF File in Microsoft

Updated July 19, 2017

Universal Disk Format (UDF) is a file system that is used when burning storage media such as CDs and DVDs. Unlike other CD/DVD file systems, UDF allows you to edit or delete the data that you may have previously burnt. Audio Video Interleaved (AVI) is a file format used to store video. You can convert an AVI file from an existing file system (NTFS or FAT32) to the UDF system by burning it onto a DVD. You can use the built-in disk-burning utility that comes with operating systems such as Microsoft Windows 7 and Microsoft Windows Vista to complete this task.

Insert a blank DVD into your computer's DVD writer. After the "AutoPlay" menu pops up, select the "Burn files to disc" option.

Name the DVD that you about to create when prompted and click "Next"

Select the "Live Files System" option by clicking the radio button next to it. Do not use the "Mastered" option. Only the "Live File System" option allows you to burn files in the UDF system.

Click "Next" and Windows will format the DVD in order to prepare it for burning. After formatting, Windows will open a Windows Explorer window into which you can either drag or copy any AVI file. After dragging or copying the AVI file, Windows will burn it to the DVD in the UDF file system.

Close the session after burning the AVI file to the DVD. To do this, open Windows Explorer, right-click the icon of your DVD writer and select "Close Session." Now you can safely eject the DVD.


Burning an AVI file to a DVD using the UDF file system does not change the file extension of the AVI file. What will change is the file system in which the AVI file is stored. You can still play an AVI file normally after storing it in the UDF file system.
