If your administrator has changed the default folder structure and you want to apply the changes then you can use the re-build folders option to do this. The re-build folders option will add any missing folders to the structure. No folders are deleted or modified by this action, only the missing folders are added.
To rebuild the folders :
Go to: Documents page.
Select the page action button in the top right and select 're-generate folders'.
The page is refreshed and any missing folders from the template have been added.
