Navigate in the same way as in Windows Explorer: click a folder in the folder structure or in the content pane to the right.
It is also possible to fast-scroll through the current path by clicking on the desired folder in the folder path (breadcrumb) above the document listing:
Inside an entry or a folder, you can also navigate between the entries or files without first having to go to the list view. Click on the arrows at the top of the entry or viewer. You can also click on the "View all entries" or "Show folder contents" buttons to return to the list view.
