pdm pro: get file path by name

I'm new to pdm pro and am trying to open a file using code (vb.net specifically).  The catch: I only have the file name, no path information.  I'm assuming there is a way to find a file using only the name  but I have been unsuccessful so far.  In my code I have been able to connect to my desired vault and I have also logged into it.  Can anyone offer any assistance?
