Abstract:

This is a review of some multiple-file search and replace utilities for the Windows operating system. One limitation in Windows is the lack of a good search and replace utility. I've often needed to do a search or search and replace across multiple files. While Windows does have a decent Find utility, it doesn't search and replace. I've found a couple of programs that address this limitation.
