GAT list both these sharing methods as different descriptors. In the screenshot above you will see examples of files shared to Public (Open to full Public) and Public (Open to Public with a link)
To find the complete list of files in each category simply click in the descriptor for the category you are interested in.
This will bring you a list of files which are Open to full Public –
This will bring all files which are Open to Public with a link.
Once you select on the options “Open to full Public” or “Open to full Public with link” or any other field from the summary table the result will be displayed below.
Admin can apply a custom filter on each result and perform bigger in-depth search including the “Sharing flags” for each file.
