filter for mp3’s that have more than one album name in the same folder?

Maybe this export script can help ...

$filename($getEnv('USERPROFILE')'\Desktop\AlbumDiff.txt',UTF-8)
$loop(%_folderpath%,1)$loop(%ALBUM%,1)%_folderpath%' === '%ALBUM%
$loopend()$loopend()

Possibly this report is a little bit more comfortable to read ...

1: $filename($getEnv('USERPROFILE')'\Desktop\AlbumDiff.txt',UTF-8)

2: $loop(0)$loop(%_folderpath%,1)$puts(MaxWidth1,$ifgreater($len(%_folderpath%),$get(MaxWidth1),$len(%_folderpath%),$get(MaxWidth1)))$loopend()
3: $loop(%_folderpath%,1)$loop(%ALBUM%,1)$left(%_folderpath%$repeat($char(32),$get(MaxWidth1)),$get(MaxWidth1))' ==> '%ALBUM%
4: $loopend()$loopend()$repeat('=',$get(MaxWidth1))$loopend()
5: $loop(0)$loop(%ALBUM%,1)$puts(MaxWidth2,$ifgreater($len(%ALBUM%),$get(MaxWidth2),$len(%ALBUM%),$get(MaxWidth2)))$loopend()
6: $loop(%ALBUM%,1)$loop(%_folderpath%,1)$left(%ALBUM%$repeat($char(32),$get(MaxWidth2)),$get(MaxWidth2))' ==> '%_folderpath%
7: $loopend()$loopend()$repeat('=',$get(MaxWidth2))$loopend()
