Show in Finder
The Tag Editor provides a very handy and quick way to jump from the spreadsheet to MP3 files in the Finder.
This can be done with the "Show in Finder" menu command, which can be found in many macOS applications. The "Show in Finder" command can be useful for operations like playing, copying, or backup.
How to use Show in Finder command
Select a few or all cells in the Tag Editor. You can do that with the keyboard shortcuts or via the top or context (right-click) menu 'Select' commands.
Right-click on the selection again to invoke the context menu. In the context menu, select the Show in Finder command.
