Rejean,
I suspect you're after a file-based source so that you can access the
tips programmatically, and I'm not sure where to find that for the two
LabVIEW versions you're interested in.
However, in the Online Help for LabVIEW 6i, there's a top-level folder
called "Quick Tips" that will let you browse through all of the tips
that are displayed at launch. If you're just looking to browse the
content, this is a good place to look.
