Think this program is great and am still learning how to use it 
So here is my question how do you block change the track names in the file column for example
i have 11 tracks that i want to change from
01 - Abba - Waterloo.mp3 to 01 - Waterloo.mp3
02 - Abba - Sitting in the Palmtree.mp3, to 02 - Sitting in the Palmtree.mp3
and so on
Also if the track name is somthink like :- 02 - Abba _ Sitting in the_ Palmtree.mp3
How do you change it to :- 02 - Abba - Sitting in the Palmtree.mp3
Thanks for a great program 
If the information is already contained in the tag of the files you can use
Converter > Tag - Filename with a formatstring like
$num(%track%,2) - %title%
Otherwise you'll have to import this information first using
Converter > Filename - Tag with a formatstring like
%track - %artist% - %title%
Do you really have such filenames? Please try to experiment with the actions.
