When sharing documents professionally, hidden metadata can expose confidential information. This guide shows you how to clean files properly before distribution.

Why Document Metadata Matters

Office documents retain extensive metadata that could compromise:

  • Confidentiality - Previous versions, comments
  • Privacy - Author details, edit history
  • Security - Hidden data, track changes

Real-World Case

A 2023 study found 78% of corporate documents shared externally contained sensitive metadata, including:

  • Employee names (62%)
  • Internal file paths (45%)
  • Previous document versions (31%)
