Need a command to delete files/ directories older than 7 days on Windows 2008r2 Server

We have a directory on a fileserver that users scan documents to.  It is suppose to be a temporary area, but users do not clean up the files.  The server path is:

\\servername\Share\scan

I would need all files and subdirectories older than 7 days to be deleted.  I am not a script person or a programmer so I not sure how to do this.

Any help would be appreciated.
