I'm dealing with some very massive SQL files and I need to be able to go in and edit them. Are their any editors that work on Windows I can use?

I need to be able to cut out what I don't need and grab the inserts I do need without the system hanging up.

Use phpMyAdmin to work with mysql. It works with a web browser and is quick. You need to set up a Web server for this along with phpMyAdmin. EasyPHP is one such WAMP server with phpMyAdmin included.

There is the MySQL Workbench, but I have not tested it with a large amount of data, yet. It was fine with a few hundred to thousand rows of data, though.

In case you just need a powerful text-editor, you can try Notepad++, in my experience the most performant editor out there.
