Hi All
I'm trying to find a way to only select files in the pane with .mp3 or .wav as their extension. Other files in the pane with different extensions would be left unselected.
Is there a way to do this with some clever code or action?
I'm trying to do this because in some folders I have .mp4 files which I don't want to include in my playlist. An automated way would avoid having to select files manually one-by-one.
Grateful for any advice.
🙂

Have a look at the powerful filter expressions of Mp3Tag:
> **[Filter and Search – Mp3tag Documentation](https://docs.mp3tag.de/filter/)**
>
> Documentation on Filter and Search and keywords to form complex filter expressions. Mp3tag is the universal Tag Editor.
In your case the filter expression would be:
%\_extension% IS mp3 OR %\_extension% IS wav

I would also recommend the filter.
But you could also sort by the column for the tag which should be different for each file type.
There is no way to keep the file list untouched and select only some files at a key stroke.

- Thanks guys - problem solved. I'm not seeing a way to save or recall filters so I guess they would need to be entered each time. Is that right?

See the documentation:
