This lets you see the files and folders that you have in the Morro Cloud Storage. The list view shows you the Size, Owner, and Modified Time and Date for each share or file.
You can navigate up and down the file structure by clicking the the file/folder view on the top of the page.
The top-level Shares can not be changed here. Once you get into a particular share, you can create a sub-folder or upload files.
For any given file, you can click the "more" icon to download, rename the file, or restore to a previous version of that file.
