Sort and Reorder Your Resources
Reorder Files or Folders
Select the Resources tool from the Tool Menu of your site.
To reorder the files in a folder, to the right of the folder, from the Actions drop-down menu, select Reorder. This displays the folder Reordering page.
Selecting and drag the items into the desired order, then select Save.
You can sort files in Resources by Title, Created By (resource creator), Modified (last modified date), and Size.
For example, by selecting the column header labeled Title, files will be sorted alphabetically from Z to A. Selecting Title again will sort alphabetically from A to Z.
