If you need to choose loads of files from a list, it might be easier if they had little checkboxes. This way, you don’t have to hold Control or Shift keys and risk something going wrong.
To add checkboxes to the top left corners of your Windows Icons, open the file manager, choose the View tab and then choose Options, Search and Folder options. Scroll down the list of options and tick Use checkboxes to select items. You can now select files and folders by ticking the little box on their name.
