Python scripts directory

Hello, I have Windows Blender Portable :smiley: on USB from PortableApps.com and I want to set “Python Scripts” File Path. But drive letter of my USB is changing and I can’t set path like:
“H:\BlenderPort\App\Blender.blender\scripts”. I tried to set relative path (".blender\scripts"), but it not work. What path I should set, or what I should do? Please help me, I am only newbie :frowning: .
