Filter document library view by file type

Sometimes we get requirement such that document library should display files with certain file type.
For an example, I want to create view which will display only word documents.

Here is how we need to create our view

1. Go to Document library settings.
2. Create view
3. Name the view: Word documents
4. Go to Filter and Select "Show items only when following is true"
5. Choose Name > Contains > .doc (See below screenshot)
6. Or When Column > Name > Contains > docx (See below screenshot)

When we will select this view it will display word documents.
