Background On M$ Win*, I don’t have dedicated PDF readers like Adobe.
During visioconference, one might want to share some downloaded PDFs. Those documents can be part of an ebook or notes. In some situations, they can provide context to a discussion.
Problem Under the same folder, you might have downloaded_ebook.pdf personal_info.pdf other_personal_stuff.pdf that you don’t want to expose while streaming. However, each downloaded PDF usually comes with a name set by others.
