FuzRegex

The FREE Lite edition of FuzRegex lets you FIND text in files using regular expressions. The PAID edition lets you FIND and REPLACE. In case you do not already know how to use regular expressions, the help menu has links to excellent references to help you learn. Regular expressions are super powerful. You can also search and replace using phrases without wildcards, but you will be missing out on most of the power of the utility. There are screenshots and more information for beginners available at FuzRegex.com.
