PowerPoint File Properties

GemBox.presentation supports two types of file properties: built-in and custom.

Built-in properties contain general information about the document, such as the title, authors, date, etc. Custom properties are those that users define, both name and value.

With the following example, you can learn how to read both built-in and custom presentation properties.
