dir structure to tags

hi there
my library is sorted in the following matter
artist name -> album name -> tracks

how can i update the tag info accordingly ?

(artist folder has his thumb)

regards
ahmad

Use Convert>Filename-Tag
Enter (something like this):

%artist%\%album%\%title%

Use the backslash \ to address folder levels

thanks m8

any good mp3 duplicates finder ? (not by name only)

similarity - that's the name.
It checks tags and contents.
