File support Required

Hello Sir, Greetings, I want to inform that mp3Tag is so far fabulous tagging software for me, but i'm facing some file issues with it. File extensions related to AVI files are not supported yet. please make available for AVI extensions also. Thanks.

You can add these file extensions in
Tools>Options>Tags.

Yet, I do not think that if will do any good because AFAIK avi files have not tags as metadata.
