Create a Action Group (FAQs: [Actions](https://community.mp3tag.de/t/967/2) ) with the following:

1. tag track #s  
Action: Format Value  
Field: TRACK  
Formatstring: %\_counter%  
(this can't reset the tracknumber for every folder. if this function is needed, you have to put this out for the actiongroup and use the Track Number Wizard, which can't be used as part of a action group)

2. rename file according to directory (track # - directory)  
Action: Format Value  
Field: \_FILENAME  
Formatstring: %track% - %\_directory%

3. get tag values from file name (title, author, album(series name) etc)  
Action: Guess Values  
Source Format: $if($eql($regexp($regexp(%\_filename%,._?( - )._?,$1),(.\* - )._,$1), - - ),$regexp(%\_filename%,(._) - (.\*),$1 - - $2),%\_filename%)Guessing Pattern: %track% - %artist% - %album% - %title%

4. change title to "title - track #"  
Action: Format Value  
Field: TITLE  
Formatstring: %title% - %track%

edit:  
step 3 adjusted according the discussion below
