Can I get or set the MP3 Unique File Identifier (UFID) with MP3tag ?
I guess I've set it with a Java program I just wrote, but I don't see it with ALT-T ?

Nope. This frame is currently not supported.
Can you send me one of the files to my [contact mail](http://mp3tag.de/en/contact.html)?
Best regards,

I will once I figured out how to correctly write one... my Java program still seems to be causing some troubles and is corrupting my MP3 ☹

Okay, so no file needed 🙂
It seems like the [MusicBrainz Tagger](http://musicbrainz.org/tagger/index.html) stores information in the UFID frame.
I'll have a look at it.

The latest [Development Build](http://developer.mp3tag.de) supports this frame now.

Great... this works fine ! (even with multiple frames). I can read it fine in Java now, the only problem is the Java library corrupts the file when I try to set it (but that's nothing you can help with).
Happy New Year !
