When you look at a site's Resources, within the Resources window you will see the Title, Size, author ("Created By"), and Last Modified date.
If you have sufficient permissions, you can click Edit
to
revise a Resource item, at which time you can also see Creation Time
and Last Modified By metadata.
To view a Resource folder's subfolders, click the plus sign
(+
) on the folder icon left of the title. You can toggle
the folder open and closed by clicking the plus sign or minus sign
(-
). If the folder icon has an arrow on it, it is too
large to be expanded.
