Try using VI Server to list the VI's in memory, and their paths.
I assume you are doing this to list the contents of a project. The above method will give you a list of all VIs in memory, so all you have to do is run it while your project (exclusively) is open. You will have to be sure you know which VIs belong to this tool so you can subtract them out by checking the status.
There is probably an easier way, though I am not sure if the SCC module allows printing of the contents of a project. I know that other Source Code Control programs do allow this. Anyway, if you were to enter your project into a SCC program, you would be able to monitor and follow the contents of the project, and not have to worry about things like this.
Good luck.
