• Software, copyright info

2. Document Metadata

• Author, title, keywords
• Creation/modification dates
• Edit history, hidden data

3. File System Metadata

• Timestamps (created/modified/accessed)
• Size, permissions, owner
• Extended attributes

4. Media Metadata

• Video: Codec, resolution, duration

Quick Reference
