Delete all fields (method to leave only cover)

Delete all fields (method to leave only cover)

Nice to meet you all in the community!
Sorry if it's hard to read because it's a translation.

Win11 environment
Version is v3.22b
The main extensions are mp3.flac.mp4.mkv

I want to remove all information except the cover (thumbnail).

So far I've been adding the tag panel manually, but sometimes there are tags missing.
And it is difficult for me to identify those tags.

I just found out about the "delete all fields" feature and was impressed when I tried it!

I thought it would be ideal if I could exclude only the cover from it, so I asked the question.

The total number of files exceeds 10,000, so I would like to avoid having to temporarily save the cover and then re-register it.

I am not adamant about the ability to delete all fields.

So any other method would be fine.

My concern is that I work with Japanese, so even if I follow your advice, it may not work because of the character encoding.

I have had other software fail because the path contained Japanese characters.
Fortunately I have been using mptag for 3 years and have never had a problem.

If anyone has any ideas on how to do this, please help.
Best regards.

Are you really sure that you want to delete all this information because it will be a lot of work to get it back?

Anyway, here we go::

Load all your files and highlight them
Define an Action: Actions -> Quick
Action Type: Remove all fields except
Fields to leave: PICTURE

I strongly recommend to test this first on o some testfiles.

Thank you.
That's really great. I'm very impressed.
