Good day. I would like to know, when I am in Mp3Tag how to go directly to the file / folder concerned in Windows? Thanks
Define your own right click menu tool ... use main menu File/Options/Tools ... e. g.

DD.20090926.0955.CEST

That's OK !
Many thanks for your help
Thanks for that DetlevD!
Can something similar be done for Total Commander?
Is there a hotkey for the tools menu?
First read Total Commander Help file, section commandline parameters.
You may try something like this as a TC parameter string with Mp3tag tool configuration dialog:
/N /L="%_folderpath%" /R="%_path%"
