OfficeFileGuard - Readme File
============================================================

PRODUCT OVERVIEW
OfficeFileGuard is a lightweight productivity and data protection
utility for Microsoft Windows and Outlook. It helps users prevent
accidental sharing of confidential documents.

KEY FEATURES
* Context Menu Integration: Mark .docx, .xlsx, and .pptx files as
  "Reserved" directly from Windows Explorer.
* Visual Indicators: A custom padlock overlay icon identifies
  protected files at a glance.
* Outlook Protection: A VSTO add-in intercepts outgoing emails and
  warns you if "Reserved" documents are being sent to external
  recipients (outside your email domain).

HOW IT WORKS
1. File Marking: The app writes a custom property to the Office
   Open XML file and logs the path in the Current User registry.
2. Shell Extension: A dedicated DLL manages the icon overlays
   in Windows Explorer.
3. Outlook Guard: The add-in monitors outgoing attachments and
   provides a confirmation dialog for external recipients.

PRIVACY & SECURITY
* No Network Access: The software does not connect to the internet.
* No Data Collection: No user data is collected or transmitted.
* System Integrity: Does not modify system files or install
  background services.
* Registry & Permissions:
  - All user settings and file paths are stored in HKCU.
  - Administrative privileges are required DURING INSTALLATION
    ONLY to register the Shell Extension Icon Overlay in HKLM.
    This is a Windows requirement for displaying status icons
    in File Explorer.

SYSTEM REQUIREMENTS
* Windows 10 or 11
* Microsoft Outlook (for the VSTO add-in features)
* Microsoft Office (Word, Excel, PowerPoint)

INSTALLATION
Run the provided installer (built with Inno Setup) and follow
the on-screen instructions.
