Rasppi-file-manager
From openmichigan
In order to make it easy for non-techies to manipulate the content on the Raspberry Pi, the server was configured to automatically make all USB storage drives visible to the web server. An open source utility, "eXtplorer", is then used to allow the content on the server to be uploaded, deleted, or changed.
To access this tool, click on the "File Manager" link on the home page.
Login in using the "pi" credentials. You will be presented with the following page:

When the device is available and mounted on the server, you will see the right frame populated.
Given that this tool resembles other common "folder" tools, the interface should be intuitive.
