In Microsoft Defender antivirus, a “Controlled Folder Access” option helps protect your valuable data from malicious apps and threats, such as ransomware.
By default, many system folders and default locations are protected by Microsoft Defender Controlled folder access. Microsoft does not allow you to delete these system folders but does allow you to add other folders to this list that you want to protect.
Adding other folders to this managed folder access can be helpful if you don’t store files in the standard Windows libraries. You can also add network shares and mapped drives.
In addition, environment variables and wildcards are supported. Finally, controlled folder access helps protect your files and data from ransomware, as only trusted apps and services can access your protected folders.
The following folders are added to controlled folder access by Windows by default. The documents folders, both under the user profile and in the public profile. Furthermore, the images, videos, music, and favorites folders are also added for both the user and public profiles.
