Just a quick note because I’m dealing with that kind of files at the moment. Whenever you have a large SQL file which is bigger than 1GB most editors need plenty of time to load such files and we didn’t talk about editing those files yet. UltraEdit for example lags a lot when opening 1gb+ files.
To be able to open, edit and save those files quickly I highly recommend WinHex. It’s not as easy as a usual Text Editor but it’s ultra fast because files are being edited just in time. Check it out, you’ll love it!
