Way to link docs on stick to apps on same

I have found a U3 app that is great for when I use other computers. It is called
AppSnapper and it will link all the docs on the USB stick to programs carried on
that stick rather than on the host computer. It is wonderful not to have to drag and drop and still not have that work sometimes.

Is there anything similar to this that can be used on a plain USB stick. As an
example: OpenOffice App loaded and 16 O.O files added to stick. How to open other than drag and drop?
Thanks,
Donna
