I can get the filename itself to pass into the track tag via actions with format value of \> field : track to format string : %\_filename% That will force file name into track tag. But all I want is the 01 part of the file name to enter into the track tag. 01 (Tony Toni Tone) Feels Good.mp3 I've tried ^.{2}%\_filename% to the field and variants to %track% but nothing seems to work. What am I missing? Can someone help me out? Thanks ---

I figured it out..... New action: Guessing Value Source format \> %\_filename\_ext% Guessing Pattern \> %track% %dummy% Filled in track with the leading track number with space delimiter. 🙂 ---
