I would have to guess you are trying to move a folder. Copies still work fine for me. However from Windows NT to 10 never solved how to clone some user account intact.
To remove the old user I use the control panel and not the delete the user account manually because... permissions are a bear.
Believe I have a corrupt user profile as newly installed apps not appearing in desktop programs menu, so decided to create two new profiles one final and one temporary, using the copy to procedure built into Windows, but used Windows enable app to allow copy to to work.....got an error message at the last step with a pop up windo telling Windows could not delete the folder.....need some help please.
