There's no way to tell S3 to delete all files that meet a specific criteria - you have to delete one key at a time.

Most client libraries offer a way to filter and paginate such that you'd only list the files you need to delete and you can provide a status update. For an example, Boto's bucket listing accepts prefix as one of the parameters.
