I know that VS2010 has a very nice compare function, but for anyone who doesn’t have VS2010 installed:
Notepad++ (the famous Notepad 2.0 application and free to download) has a free plugin called ‘Compare’ which enables you to easily compare all sorts of text-based files. For example SQL, XML, anything you’re able to open with NotePad++!
How does is look like?
How to get it and install it?
#1 Download NotePad++:
#2 Download the NotePad++ Compare plugin:
#3 Unzip the plugin’s DLL-file (ComparePlugin.dll) and copy it to:
[NotePad++ install folder]\plugins
#4 Start NotePad++ and verify that the Compare plugin is enabled under:
Plugins -> Compare
#5 Open two files, like shown here:
#6 Start comparing!:
Go to Plugins -> Compare -> Compare (or use Alt+D)
