Problem when only some files have info for tag

Hi all, this is my first post.

I've just installed Mp3Tag today, and I'm trying to tag some files using the "Convert/Filename-Tag" dialog. Some of the files I want to tag have comments. Unfortunately, if I select a group of files where some don't have comments, Mp3Tag doesn't want to tag any of the files.

For instance, if I select only:

Beatles\Ultra Rare Trax\07 - Misery - [Take1].mp3
Beatles\Ultra Rare Trax\08 - Norwegian Wood - [Take 4].mp3

...then %artist%\%album%\%track% - %title% - [%comment%] works fine. But if I select:

Beatles\Ultra Rare Trax\05 - I Am The Walrus.mp3
Beatles\Ultra Rare Trax\06 - Leave My Kitten Alone.mp3
Beatles\Ultra Rare Trax\07 - Misery - [Take1].mp3
Beatles\Ultra Rare Trax\08 - Norwegian Wood - [Take 4].mp3

...then Mp3Tag won't tag any of the files.

Is there any way to get Mp3Tag to bypass the uncommented files? I don't want to have to perform separate tagging operations, because I have over 20,000 to tag. Any help/advice much appreciated!

You can use the Filter F3 to filter for [ and invert the result for the second pass.

Kind regards,
Florian

I'll give that a go, thanks!

(update) That works great. Thanks again!
