# Trouble file StringProperty subtype FILE_PATH

I have a StringProperty(subtype="FILE_PATH) and I am trying to make it so the user selects a folder and then a file is saved out to the location, but the filepath comes out looking really funky.

The folder selected is D:\Pictures, what the StringProperty shows is //..\..\. What is going on here?

// indicates a relative path in Blender.
Or you can convert a relative path to a absolute path using the built in method bpy.path.abspath(path)
