File Associations in Eclipse

This might be quite simple for most, but I ended up spending half an hour to find this option in Eclipse. I am using eclipse for velocity editing and by default the associated files are vm and vsl, however the velocity files that I had were vmd, so wanted to associate vmd with velocity editor. For all of those who have shared my pain, the option is available under the tab of Windows -> Preferences -> General -> Editors -> File Associations.
