Probably the best string/text-replacement software around (and it's free). ReplaceEm, is a freeware string-replacing utility for Windows. At its core, ReplaceEm is essentially a text search-and-replace program. However, unlike the search-replace functionality of a standard text editor, ReplaceEm is designed to operate on multiple files at once. And you need not only perform one search-replace operation per file -- you can setup a list of operations to perform. If different groups of files need to have different operations performed on them, this is no problem either. And the best feature of all is that you can also specify a backup file for each file processed just in case the replace operation didn’t do exactly what you wanted.ReplaceEm's official site and download area is here.
