7 Essential Tips for Secure File Sharing in Windows 11

In today’s digital world, sharing files is as routine as making a cup of coffee—but when those files are sensitive, you need to be extra cautious. Windows 11 brings several built-in tools and features that make protecting your data more intuitive than ever. In this article, we’ll walk through seven hands-on tips to ensure your confidential files stay private. Whether you’re sending documents to your boss, transferring personal photos, or sharing proprietary business data, these expert techniques will help you secure your files from prying eyes.

1. Remove Metadata for True Privacy​

When you create a file, it’s not just the content that gets stored. Hidden metadata—such as the author’s name, creation date, and even the device information—can inadvertently expose details you’d rather keep confidential.
How to Remove Metadata on Windows 11:

• Open File Explorer: Press <kbd>Windows+E</kbd> and navigate to the file.
• Access Properties: Right-click the file and select Properties.
• Head to the Details Tab: Click on the Details tab to view metadata.
• Remove Personal Information: Scroll to the bottom and click Remove Properties and Personal Information.
• Create a Clean Copy: Choose Create a Copy With All Possible Properties Removed, then click OK.

By sharing the copy created by File Explorer, you ensure that any hidden personal data stays behind.
Summary: Removing metadata is a quick and effective first-line defense that keeps your identity and sensitive details under wraps.

2. Encrypt Your Files Before Sharing​

Even if someone intercepts your file, encryption makes the content unreadable without a password. Applications such as 7‑Zip and WinRAR provide reliable encryption options that turn your file into an indecipherable archive.
Steps to Encrypt with 7‑Zip:

• Install 7‑Zip: Download and install 7‑Zip, then restart your PC for a fresh start.
• Locate Your File: Open File Explorer, right-click your file, and select Show More Options > 7‑Zip > Add to Archive.
• Enter and Confirm Password: In the dialogue, fill in the Enter Password and Reenter Password fields.
• Create the Archive: Click OK to generate your encrypted file.

Why encrypt? With encryption, even if your file is intercepted, only someone with the correct password can decode the content.
Summary: Encryption turns sensitive data into digital gibberish for unauthorized eyes—ensuring that even if the file is compromised, your data remains secure.

3. Opt for Peer-to-Peer File Sharing Providers​

Many traditional file-sharing solutions store your files on central servers, which can be a target for cyberattacks. As a safer alternative, consider using peer-to-peer (P2P) file-sharing services that send the file directly from your device to your recipient’s computer.
Use Send Anywhere for Secure Transfers:

• Visit the Send Anywhere Website: Open the site in your web browser.
• Upload Your File: Click the plus sign, select your file, and choose the file from your device.
• Send Directly: Under the file list options, click Direct then Send to generate a unique download code.
• Share the Code: Provide the recipient with the download code so they can access the file directly.

Rhetorical question: Why let your sensitive file sit on a vulnerable server when you can transfer it directly?
Summary: P2P sharing bypasses central storage, reducing the risk of interception and improving your control over who accesses your data.

4. Utilize End-to-End Encrypted Email Services​

Sometimes, email is the preferred file-sharing method. But to shield your attachments from unauthorized access, use an email provider that offers end-to-end encryption—ensuring that only you and your recipient can access the shared file.
What to Consider:

• Proton Mail: A popular option, even on its free plan, Proton Mail provides robust end-to-end encryption.
• Secured Attachment Transmission: With encrypted email services, your files are transformed into unreadable data unless the recipient decrypts them.

Summary: End-to-end encryption in emails ensures that even if someone intercepts the data mid-transit, the file remains secure and confidential.

5. Share Safely with Secure Instant Messaging Apps​

If you choose to share a file via instant messaging, opt for applications that support end-to-end encryption. Popular apps like Signal, Telegram, and WhatsApp can provide an extra layer of security for your file transfers.
Key Points to Remember:

• Signal: Ideal for smaller file sizes (up to 100MB) with robust encryption.
• Telegram: Offers secure chats with large file transfers (up to 2GB); just remember to enable its Secure Chat feature.
• WhatsApp: Also supports encrypted file sharing, although be sure to adjust backup settings as cloud backups may not be encrypted by default.

Summary: When using messaging apps for file sharing, turning on end-to-end encryption protects your data throughout the communication process.

6. Split Files for Added Security​

For an extra layer of defense, why not split your file into smaller chunks? This way, even if one part is compromised, it’s nearly impossible for an interceptor to piece together your complete file.
Splitting Files Using 7‑Zip:

• Launch 7‑Zip: Open File Explorer and locate your file.
• Open Archive Options: Right-click the file, then select Show More Options > 7‑Zip > Add to Archive.
• Configure the Split Size: In the Split to Volume, Bytes field, specify the chunk size (e.g., "5MB" for a 10MB file to be split into two parts).
• Enable Encryption (Optional): Enter a password to secure each chunk if desired.
• Send the Chunks Separately: Transfer each file part individually to the recipient. They can reconstruct the file by extracting the first chunk.

Summary: File splitting minimizes risk by ensuring that even if one segment is intercepted, it cannot be reassembled without the rest of the pieces.

7. Limit File Access on Cloud Storage Platforms​

Cloud storage solutions like Google Drive and OneDrive are convenient, but they come with their own set of risks. When sharing files online, limiting access—such as setting files to view-only—can prevent unwanted modifications or access.
How to Restrict File Access:

• On Google Drive:
• Right-click the file and select Share.
• Enter the recipient’s email address and assign them Viewer or Commenter permissions.
• On OneDrive:
• Right-click the file and click Share.
• Configure permissions (e.g., choose Can View instead of Can Edit).
• For Microsoft 365 premium users, you can generate a link that expires after a set period.

Summary: Controlling file permissions on cloud platforms greatly reduces the risk of unauthorized changes or prolonged exposure of your sensitive data.

Final Thoughts​

If you’re serious about protecting your sensitive files on Windows 11, these seven tips offer a robust roadmap:

• Strip Metadata: Eliminate hidden data that can expose personal details.
• Encrypt Files: Ensure that intercepted files remain unreadable.
• P2P Sharing: Bypass vulnerable central servers.
• Encrypted Emails: Limit exposure during transmission.
• Secure Messaging: Harness the power of end-to-end encryption.
• File Splitting: Divide and conquer potential intrusions.
• Controlled Cloud Access: Fine-tune permissions to expire and restrict access.

Each step addresses a specific vulnerability, offering a multi-layered defense against unauthorized access, hacking, and other digital threats. By integrating these methods into your routine, you’re not just sharing files—you’re sharing them wisely.
