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). Regular expressions, case-insensitive, whole-word, and whole-line searches are supported. ASCII, Unicode, and UTF-8 files are supported. A detailed log is kept of every string that is found and replaced. String-O-Matic is a professional, rock solid program – don't trust your files to anything less!
