It's not surprising that all this power doesn't get utilized because just as one begins to learn their way around along comes new software that requires a new learning curve. Copying and pasting is so useful I don't know what I'd do without it. One can copy just about anything you see in your PC or on the Internet. It remains there until something else is copied on top of it or your PC is shut down. Once on the clipboard numerous copies of the information can be pasted to just about anywhere.
Text is the most copied item but one can copy folders, files, graphic images, sounds, music, etc.
You can even copy pictures on web pages by right clicking on them. Suppose you have a folder full of data files on the C drive and you want to move a copy of the folder and its contents to the D drive. There's several ways to do this. Another way is have both folders showing on your desktop by shrinking their displays if necessary. With the CTRL key down drag the file with the mouse from one folder to the next.
