ReNamer is a very powerful and flexible file renaming tool, which offers all the standard renaming procedures, including prefixes, suffixes, replacements, case changes, as well as removing contents of brackets, adding number sequences, changing file extensions, etc.
For advanced users, there is RegEx support and a PascalScript rule, which lets users program their very own renaming rule.
