i want to be able to add disc numbers like '1-' to filenames in batch. currently i have to copy and paste the 1- manually in front of the filenames and it's tiring. i already have the songs prenumbered e.g 01,02,03. but need them to be 1-01, 1-02, 1-03... 2-01, 2-02, 2-03 as disc 2 etc. thanks

you can use Convert-Tag-Tag for  
Field: \_FILENAME  
Format string: $num(%discnumber%,2)-%\_filename%
