How do I double click on RW 5 to upgrade to RW6?

Just downloaded RW 6 and have followed directions for upgrading until I get to double click on document. Where do I double click? I am a novice.

After you’ve downloaded and upgraded Rapidweaver 5 to version 5.4.1, then you open your version5 site files in Rapidweaver 5 (by using the File>Open menu item or double clicking your sitefile.rwsw). Once open, then SAVE them all. Only then can you open them in Rapidweaver 6 using the menu item File>Open the same saved site files. It will convert them to sitefile.rw6.
