.desktop file KDE Service menu - how to copy many files

I have a servicemenuitem for KDE which copies the selected file to the desktop. It works when one file is selected on the desktop, but when multiple files are selected, they are not copied. The -exec parameter "%F has a list of all files and their full paths in, but I don't know how to get this to work with the -cp command. Thanks [Desktop Action copytodesktop] Exec=cp "%F" /home/acer1/Desktop Name=Copy To Desktop Icon=document-send [Desktop Entry] Actions=copytodesktop ServiceTypes=KonqPopupMenu/Plugin MimeType=all/all; Type=Service X-KDE-Priority=TopLevel
