When using word or adobe, we usually move the file to a folder window to save it there, by dragging the mini icon in the header of the file window. However, Adobe has changed its understanding of dragging that header icon : whenever you drag that icon to a different header, you actually create a shortcut of your pdf file in that location instead of moving the file there.
So how to move?
When you click and drag, please hold the "alt" key ("option" on Mac). You will be moving the file instead of creating a shortcut.
