Make the source and destination folders visible:
Open a File Manager view of the contents of the destination folder.
Or, open a File Manager view that shows the icon of the closed destination folder.
Select the file or folder to be copied.
Press and hold the Shift key and the Control key while dragging and dropping the icon of a file or folder onto the icon of a new folder.
When you drop the icon, File Manager creates symbolic link in the new folder that points to the original file or folder. Make sure that you release the mouse button before you release the Shift key and the Control key. Otherwise, you will move instead of link the file or folder.
