See the extended tags dialogue for fields that can be found in the files and that are not OS properties.

Use the found field variable name to create further columns or tag panel fields.

To copy the contents of one tag field to another, see

> How to copy one field value to another field? Example how to copy the content of the ARTIST field to the ALBUMARTIST field: Create a [new action](https://community.mp3tag.de/t/actions/967/2) in an existing action group or make a new action group. Action type: Format value Field: ALBUMARTIST Format string: %artist% Note: If you want to copy all possible values of a field (in case you have multiple artist fields), the internal scripting function [$meta\_sep](https://docs.mp3tag.de/scripting) can be used in the format string, e.g., $meta\_sep(artist,\\\\)
