As you click on folders and move around in the files app you will see your path in the white box near the top of the page. The folder names are also hyperlinks and you can click on them to move directly to that folder.
When you are uploading files you will see the full path of the folder that the files are being uploaded into along with the task name that you are doing.
If you move files you will see the root folders, sub folders and sub sub folders. Again you will see that you are in the files area and doing the Move task in the white box near the top of the page.
