7 Tips for Sharing Sensitive Files on Windows 11

Securely Sharing Sensitive Files on Windows 11: A Comprehensive Guide

Sharing sensitive files requires careful consideration of security. This guide outlines seven effective methods to protect your data when transferring files on Windows 11.

1. Remove Metadata:

Before sharing any file, especially images, remove embedded metadata (like location data). In File Explorer, right-click the file, select "Create a Copy With All Possible Properties Removed," and click "OK." Share the copy; the original file retains its metadata.

2. Encrypt Your Files:

Encryption renders files unreadable without the correct password. Use free tools like 7-Zip or WinRAR. In File Explorer, right-click your file, select "Show More Options > 7-Zip > Add to Archive." Set a strong password in the provided fields.

3. Utilize Peer-to-Peer Sharing:

Peer-to-peer (P2P) services transfer files directly between devices, enhancing security compared to cloud-based methods. Send Anywhere is a good example. Generate a download code on your device and provide it to the recipient.

4. Employ End-to-End Encrypted Email:

For email transfers, use a service offering end-to-end encryption (E2EE), like ProtonMail. E2EE ensures only sender and recipient can access the file.

5. Leverage Secure Instant Messaging:

Secure messaging apps like Signal, Telegram (using Secure Chat), and WhatsApp (with encryption enabled for backups) provide E2EE for file transfers. Be mindful of file size limits (Signal: 100MB, Telegram: 2GB, WhatsApp: 2GB).

6. File Splitting for Enhanced Security:

Splitting large files into smaller parts adds another layer of protection. Use 7-Zip to split the file, specifying the desired chunk size (e.g., 5MB). Remember to password-protect the archive. Send each chunk separately.

7. Control Cloud Storage Access:

When using cloud storage (Google Drive, OneDrive), restrict access to "Viewer" or "Commenter" levels instead of "Editor" to prevent unauthorized modifications. On OneDrive, consider using expiring share links (Microsoft 365 premium feature).

These methods, used individually or in combination, significantly improve the security of your file sharing practices. Remember to always practice good online safety habits.
