You can copy a file or folder by dragging it with the mouse, or with the copy and paste commands. The following sections describe these two methods.
To copy a file or folder, perform the following steps:
Open two file manager windows:
Drag the file or folder that you want to move to the new location. Press-and-hold Ctrl either before or during the drag. If the new location is a window, drop it anywhere in the window. If the new location is a folder icon, drop the item you are dragging on the folder.
To copy the file or folder to a folder that is one level below the current location, do not open a new window. Instead, grab the file or folder, then press-and-hold Ctrl. Drag the file or folder to the new location in the same window.
For more on dragging items, see Section 6.6.4 ― Drag-and-Drop in the File Manager.
