Tag & Rename Meta-tag Software (taging songs from file name)

Tag & Rename Meta-tag Software (tagging songs from filenames).
I am trying to tag song title from the file name for mp3. each of the file names has a number. for example 04 DEADPOOL.mp3 is filename. I want to remove the first 3 spaces of the filename. I also want to capitalize first letter of 04 DEADPOOL.mp3 in the title and the rest of the name in small letters. to read Deadpool.
Anyone know the masking editor command for this
