Search and Replace Utility

A.F.9 lets you edit files by replacing characters or any other bytes. You can edit many files in one operation, replace several search phrases at a time, use characters, decimal values or hexadecimal values for your search and/or replace argument. Besides, ou can edit really large files, since A.F.9 doesn't need to load the entire file into system memory.

ReplaceEm is essentially a text search-and-replace program. It is designed to operate on multiple files at once.

InfoRapid Search & Replace is one of the most powerful text retrieval programs currently available for Microsoft Windows. With its built-in converters, it's excellently suitable for searching and previewing HTML and RTF documents.
