Sorry for the inconvenience. The current scenario is due to policy restriction. Currently, the policy of secure folder to do the same is no longer available. Any files on it cannot be move out to the personal side where the is lack of securiity. This is due to policy restriction. Policy of secure folder was gone due to that, you couldn't move out of files to personal side. There's two way to get data.
