By default documents and folders will be ordered alpha-numerically by title. You have the option to sort documents and folders by column in both ascending and descending order. To sort by column, simply click the column header that you wish to sort by, for instance if you wanted to sort by date created, you would click the column header that says "Date Created" and the documents and folders would automatically sort by date in ascending order. Click the column a second time to sort in descending order.
Refreshing the page will revert to the default sort. If you wish to resort document and folders permanently, you should rename them
in alpha-numeric order, it may help to put a "0001. " prefix in front of documents so that they are displayed in the correct order.
