BK ReplaceEm - Version 2.0 Your premiere-quality, freeware string-replacing utility. At its core, BK ReplaceEm is essentially a text search-and-replace program. However, unlike the search-replace functionality of a standard text editor, BK ReplaceEm is designed to operate on multiple text 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 incase the replace operation didn’t do exactly what you wanted.
