Renaming multiple files

I have a folder with 2500+ files that all have a number before the actual filename. I want to sort these files alphabetically but they're all in the format #### - filename. Is there anyway to get rid of the numbers in front of each name at one time? There's no way I'm manually renaming that many files.

 

Rename files.

 

I used the first one listed...LupasRename. It worked like a charm. Thank you so much.

 

I have not tried that one. I will have to check it out.
