Which of the following is NOT typically included in system metadata?

The correct answer is that document content is not typically included in system metadata. System metadata refers to information created and maintained by the operating system or file management system that describes various attributes of a file or system resource. This can include details such as the file creation date, last modified date, and file size.

File creation date and last modified date provide a timeline of when a file was created and last changed, which is crucial for organizing and retrieving files. File size indicates the amount of space the file takes up on the storage medium, which can be important for managing storage capacity.

In contrast, document content encompasses the actual information or data contained within the file, such as text in a document or images in a photo. This content is not considered metadata because it is not descriptive of the file's attributes or characteristics; it is the subject of the file rather than information about the file itself. Therefore, document content does not fall under the definition of typical system metadata, making it the correct choice in this question.
