Searching through many files to find a specific string, word, or pattern can be time consuming and a pain. But that is in the past. With AstroGrep, a free to use OpenSource program, you can search unlimited files at once to find what you are looking for. It also lets you search by Regular Expressions to find specific patterns, search with case sensitivity on or off, and search by file create date. You even have the ability to change what file names and extensions to look for to even further your search. I personally use this program all the time to find functions in my older code that I need to look at again. It makes it much easier than opening up multiple files and trying to remember specifically what I called it.
