I'd love a right mouse action to open the containing folder (in Windows Explorer) of a file that's in the MP3TAG list. It would make a number of clean-up operations I do frequently a lot easier.
Add the following in File>Options>Tools
Create a new entry
Enter a fitting name, e.g. Explorer
Enter the fully qualified filename, probably c:\windows\explorer.exe
Enter as command line parameters: /e,/select,"%_path%"
Save this.
The function is now available in the files list context menu, submenu Tools
THANK YOU !!
Best, Michael
Searching the forum brought me to this old thread 
Tried on Windows 7, works perfectly.
Just to point out the /e option seems superfluous.
