How to leave existing tag values?



I'm wondering if there is any way to 'leave alone' any existing tag values while processing tags.

Here is my scenario:

  • I have songs where the title tag is empy
  • I also have songs where the title tag has values
  • I want to update my tags from the filenames, specifically I go Convert > Filename - Tag > Format String: %artist% - %title%
  • The above convert will update all the Artist and Title tag values from the files, but it will ALSO over-write any existing tag values with the filename values - I don't want it to do that, I want it to only update (fill in) the empty Artist and Title tag fields, but if the fields already have values, I want those to be left alone (not over-writen).

Is there any way to do this?


No, just sort the files in Mp3tag's file view by clicking on the column headers to identify files with the missing information.
