ignore prefix

[dacook]

Hi,
I spent quite some time looking for a solution to have a prefix in the movie-directory-name, but havn´t found a solution yet.
Would you please be so kind to assist?
Is it possible to ignore a index-prefix (specified by a character, e.g. "_") in scraping?
 
example 1 numeric index:
Star.Trek.Collection
    01_Star.Trek.The.Motion.Picture.1979
        movie.mkv
        movie.nfo
    02_Star.Trek.The.Wrath.of.Khan.1982
        movie.mkv
        movie.nfo
    03_Star.Trek.The.Search.for.Spock.1984
        movie.mkv
        movie.nfo


example 2 date index:
Dustin.Hoffman.Collection
    1967_Die.Reifeprüfung
        movie.mkv
        movie.nfo
    1969_Asphalt.Cowboy
        movie.mkv
        movie.nfo
    1970_Little.Big.Man
        movie.mkv
        movie.nfo
