title: Notepad++ - How to search files for a missing string
body: <p>I have cluster of 10 folders, each with 1000 program files.  I need to search these text files for a string.  All files must start with $O123456.MIN% (123456 bearing random file names).  I know how to find if the string exists, but how do I identify if the string does not exist?</p>
