String-O-Matic performs search and replace operations with multiple strings in multiple files. It was designed specifically for computer programmers working on large projects with many source code files, however any type of file can be used, including HTML. Search and replace operations can also be performed on filenames (mass renaming). A detailed log is kept of every string that is found and replaced. Regular expressions, case-insensitive, and whole-word searches and are supported. String-O-Matic is a professional, rock solid program – don't trust your files to anything less!
