Split db and have backend on local PC

I want to split my db for other reason than to share with tons of people and
I need the backend on the local machine with the front end but in a
different directory. The db front and backend will be
distributed as a packaged solution to a singler user. The user will install
the access runtime as well as the db's.
When I try to split the db called My Jewelry Project and place the backend
in a folder called My Jewelry Data using this address //My Document/My
Jewelry Data/JeweryData.accdb
it will not find the location....even though the folder exists....

I've tried ~/bla bla bla and ~//bla bla bla and these links do not work
either.

So how do I split a db and have the backend on the same computer with a
relative path?
Thanks,
