Opening one PDF with a button on a second PDF in the same folder even after the folder is moved
I have several PDF's in the same Folder/Portfolio. I have buttons on the main PDF that open other PDFs from the same folder. I have gone to the buttons's properties box, choosen the "action" tab, gone to the "select action" dropdown menu, chossen the "open file" selection and then when a window opens selected the file I want the button to open. This arrangement works fine until I move the folder to another location on my computer or I send it to someone else.
I have tried without success to find a JavaScript or orher procedure that will not be thrown off by a change in the folder's location.
Thank you for your time and hopelfully help.
