Frequently Asked Questions
What does it mean when I receive the error 'You can't connect to the file share because it's not secure' on Windows 10?
This error occurs because the shared folder requires the SMB1 protocol, which is considered obsolete and insecure. Windows 10 versions 1709 and later do not have SMBv1 installed by default due to security concerns.
How can I access a shared folder that requires SMBv1 on Windows 10?
To access a shared folder that requires SMBv1, you need to manually enable the SMB 1.0/CIFS File Sharing Support feature. Go to Control Panel -> Programs and features, then click 'Turn Windows features on or off'. Expand 'SMB 1.0/CIFS File Sharing Support', check the 'SMB 1.0/CIFS Client' option, and press OK. Finally, restart your PC.
Why is SMBv1 protocol not installed by default on newer versions of Windows 10?
SMBv1 is considered obsolete and insecure, as it makes systems more vulnerable to attacks. Therefore, starting with Windows 10 version 1709, SMBv1 is not installed by default to enhance security.
What should I do if enabling SMBv1 does not resolve the connection issue?
If enabling SMBv1 does not resolve the issue, ensure that the network settings are correct and that the share is accessible from other devices. It could also be helpful to verify the shared folder's permissions and consult additional support or resources.
