I did the following to achieve an UI for taking in path file
bpy.types.Scene.skeletonImporter = bpy.props.StringProperty(name="Import skeleton.xml path", default = "", description="Import which skeleton.xml file?", subtype = 'FILE_PATH')
bpy.types.Scene.meshImporter = bpy.props.StringProperty(name="Import .mesh path", default = "", description="Import which .mesh file?", subtype = 'FILE_PATH')
which give me this relative path when I try and open a file.

However, I wish to take in the absolute path for my files. How do I go about doing that?
There's no subtype called ABS_FILE_PATH (which would be useful in my situation).
