file default editor is changed `Eclipse`

I have an opened project in Eclipse. I have some special extensions like *.VW,*.RW and many. If I double click those files in Eclipse, it will automatically open in default eclipse text editor.

Problem: Unfortunately, I have opened *.RW file with Notepad (via file system).

Now, if I double click those files in开发者_运维知识库 Eclipse, it is getting opened in Notepad only :(. How do I reset the default editor?

Thanks

Right click and Open with ... should the opening behaviour in eclipse. Furthermore you can set the behaviour in Preferences -> General -> Editors -> File Associations.
