Path in the GPO console
Computer Configuration\Administrative Templates\OneDrive Description
This setting lets you disable the default list of file extensions that are excluded from being uploaded to OneDrive or SharePoint. If you enable this setting, the sync app will not load the default ignored extension list. Any existing files that were previously ignored due to the default ignored extension list will start syncing.The OneDrive sync app must be restarted after this setting is enabled for the setting to take effect. If you disable or do not configure this setting, the sync app will load the default ignored extension list and continue to ignore files based on the default rules.
