How to identify untagged mp3

[Kerr]

I have 5 gb music collection. In some files are tagged and some not. Is there any way to read all the tags in all the folders/sub folders? I don't want check every folder separately to see every MP3 is tagged or not.

Thanks

Sometimes we get mp3s that are not tagged with the title and artist. Traditionally, the audio CD format does not include the disc name or the name, so that an additional database is required to view this information, when discs are equipped with modern media systems.

• select all the files that you change date then use the right mouse button and choose Send To> Auto-tag:
  
• This opens a new window, the status of the individual MP3 files queried against the Grace note database
  
• Once the status is queried, so the information can be retrieved by clicking the file once and after the tag information on the lower right part of the window:
• Once all of the file the status says "Done" button to accept the changes, the tag information on these files. Es aktualisiert die Dateien "Tags in ein paar Sekunden. It updates the files' tags in a few seconds.

You can also check the written day by using Alt-F3 on a track in the playlist.
