Save the following as Unblock-Folder.ps1 :
When a file is downloaded from the internet or received from an external source, Windows may mark it as blocked to prevent potential security risks. This is done by adding a zone identifier to the file's properties, which indicates that the file came from an untrusted source. While this feature helps to protect the system from malicious files, it can also cause problems when working with files from trusted sources that have been incorrectly flagged as blocked.
