Set default application to open files by double click

[helperman]

I really like how you open associated files in Notepad++ at a certain line where match was found. I would like to open all text files (source code files) in Notepad++ despite the application it was associated with. For example, html-files are usually opened using web browser but when it comes to searching through a folder with these files I would like to open it at a certain line in Notepad++ or any other text editor.

configure notepad++ as the editor (click the settings button). Then on right-click the top entry in the context menu will open the file with notepad++.
