Using Notepad++’s built in compare feature

From time to time I need to compare text files containing configurations, xml documents, text files and sometimes PHP files. All I have to do is fire up my free open source notepad editor and use it’s build in compare feature. You open up two documents in two separate tabs. This can be achieved by simply opening two documents. Go ahead and try it we will wait.

Plugins – Compare – Compare

You will see the differences highlighted between the two documents or a message telling you that the documents are identical.
