Sharing files and folders on Windows is an essential skill, whether you’re working from home, collaborating in an office, or just wanting to stream photos and music across your devices. However, ensuring your shared files are accessible to the right people—and protected from the wrong ones—requires understanding and managing Windows permissions correctly. This guide walks you through the most important file sharing and permission tips, with clear steps for beginners and advanced users.
For Beginners: Getting Started with Windows File Sharing
1. How Do I Share a Folder on My Local Network?
Right-click the folder you want to share and select “Properties.”
Go to the “Sharing” tab and click “Share.”
In the “File Sharing” window, type the name of the user (or “Everyone” for broad access) and click “Add.”
Choose the permission level: “Read” (view only) or “Read/Write” (view and edit).
Click “Share” and then “Done.”
Your folder is now shared with the selected users on your network.
2. How Can I See Which Folders Are Shared?
Open File Explorer and navigate to “Network.”
Click on your computer’s name to view shared folders.
Alternatively, type “\\localhost” in the File Explorer address bar to see all shared folders on your PC.
3. How Do I Stop Sharing a Folder?
Right-click the shared folder, select “Properties,” then “Sharing.”
Click “Advanced Sharing,” uncheck “Share this folder,” then click “OK.”
This removes the folder from your shared list.
4. How Do I Access Shared Folders from Another Computer?
On the other computer, open File Explorer.
In the address bar, type “\\ComputerName\SharedFolder” and press Enter. Replace “ComputerName” with the actual computer’s name and “SharedFolder” with the shared folder’s name.
If prompted, enter the appropriate credentials.
5. What Are the Basic Permission Levels?
Read: Users can view and open files, but not modify or delete them.
Write: Users can add files or make changes.
Full Control: Users can do anything—read, write, modify, delete, and change permissions.
Set these when sharing folders to control access.
For Advanced Users: Fine-Tuning Permissions and Security
6. How Do I Set NTFS (Advanced) Permissions?
Right-click the folder, select “Properties,” then go to the “Security” tab.
Click “Edit” to change permissions for specific users or groups.
Add users or groups by clicking “Add,” then assign permissions: Full Control, Modify, Read & Execute, List Folder Contents, Read, Write.
Click “OK” to save. NTFS permissions provide granular access control, overriding basic sharing permissions if there’s a conflict.
7. How Can I Audit Access to Shared Files?
In the “Security” tab, click “Advanced,” then “Auditing.”
Click “Add,” select a user or group, and choose which actions to audit (e.g., read, write, delete).
This helps you track who accesses or modifies files, useful for sensitive data or compliance.
8. How Can I Share Files with Password Protection?
HomeGroup is no longer supported, but you can require users to log in with a username and password:
Open “Control Panel,” go to “Network and Sharing Center.”
Click “Change advanced sharing settings.”
Scroll to “Password protected sharing” and turn it on.
Now, only users with valid accounts on your PC can access shared files.
9. How Do I Map a Network Drive for Quick Access?
Open File Explorer, go to “This PC,” and click “Map network drive” in the toolbar.
Choose a drive letter, enter the folder path (e.g., “\\ComputerName\SharedFolder”), and check “Reconnect at sign-in” if you want it to persist.
This allows you to access shared folders as if they’re local drives.
10. How Can I Clean Up and Secure Old Shares and Permissions?
Over time, shared folders and permissions can become cluttered, leaving files exposed. Use Glary Utilities to help manage and optimize your system:
Open Glary Utilities and go to the “File Management” or “Privacy & Security” modules.
Use the “File Shredder” to securely delete sensitive files.
The “Disk Cleaner” and “Tracks Eraser” tools remove old logs and traces.
Glary Utilities can also analyze disk usage and find duplicate files, helping you remove unnecessary shared content and tighten folder permissions.
This not only improves security but frees up storage space and boosts performance.
Extra Tips for All Users
Always use strong passwords for user accounts, especially when enabling password-protected sharing.
Regularly review your shared folders and permissions to ensure only the right people have access.
Update Windows regularly to patch any security vulnerabilities that could affect file sharing.
If sharing files over the internet, consider using secure cloud services or encrypted file transfers instead of Windows file sharing.
By mastering these file sharing and permissions tips, you can collaborate efficiently, keep your files secure, and maintain a clutter-free system. Whether you’re just sharing family photos or managing a small office network, these steps will help you get the most out of Windows’ powerful sharing features.
