Replace Text, formerly called BK ReplaceEm, is the free string-replacing utility for Windows.
At its core, Replace Text is essentially a text search-and-replace program. However, unlike the search-replace functionality of a standard text editor, Replace Text 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. You can also specify a backup file for each file processed, just in case the replace operation didn't do exactly what you wanted.
"This little stand-alone search and replace utility is very handy if you need to make changes to a whole range of text, HTML, XML or other text-based files:"
