1, select the file or folder you want to delete, right click on the folder --> Properties - ->Switch to “Security<;tab-->click the “Advanced” button--> at the bottom right to switch to “Owner> tab-->Click below“Edit ”Button--> In the "Change owner to" box, click on your current username, change the owner of the file to the current username, such as Administrators, and check "Substitute" And the owner of the object & rdquo; option (folder), all the way to determine, so that you have ownership of the folder.
