"When you create a link, it stores both the relative and absolute paths. In the PI ProcessBook Define Button dialog, when the Use relative path before absolute path box is checked, the program checks the relative path first. When this option is not checked, the program checks the absolute path first. If you are moving files around for two kinds of users then you may prefer the relative path (check the box). On the other hand, if the files move individually and the directory structure might change, it is better to prefer absolute paths (uncheck the box)."
So that if you save a display1 on c:\temp and points a button to a display2 in desktop and later on you move display2 to c:\temp it won't break the link if the Use relative path before absolute path option is checked.

Hello,
Per the manual

Hope this helps.
