This tab displays basic information about the document, such as its file path, page size, and total number of pages. Clicking the file path opens its containing folder; if the file was opened from a cloud service, this opens the temporary local folder where it’s cached. The person who created the document in the source application may have set the title, subject, author, and keywords. You can easily edit the document information within the PDF document, a useful way for searching and indexing files.
