General Explainations - Refresh Metadata, Database

thomsob

Hi, this I am sure, is a rather inane question, so my appologies! But I have been trying to find basic explainations as to what some of these buttons/functions in the admin area actually do! For eg. what does 'refresh metadata' do? Where does it refresh from? Does it go back to the upload link and look on the computer??!! I have similar basic questions about many of the functions! Can someone tell me where all this info might be please (see! can't get more basic than that!!)
