When a document is created, it contains metadata. Documents displays the following metadata for each document:
Title: the name of the document, which can be edited;
Source: the path to the folder containing the document;
Date Modified;
Type: the file format of the document.
To see a document's properties:
Click the check button to switch to selection mode.
Select a document.
Click the Properties button at the right end of the button bar.
Some types of documents (e.g. PDF files) can be password protected, preventing access to their metadata or content.
Documents does not currently offer any mechanism to add privacy to a document. You may be able to do this from the application you used to create the document (e.g. LibreOffice or Adobe Acrobat).
