When you click on the folder you get a list view of all records in it by default.
Provided you want to always see a bit modified view in the folder - create a default view (visible to you only as it is a per user setting):
Open a folder
Create a view and save it
Click on the view selector (as on the pic below) [All (folder name)]
Click on the "House" icon next to the view you want to make default
Now you will see this view every time you select a folder.
