Import external py script into blender script? I wrote a py script for a custom export. I'd like to append that script to my blend file and call it using some parameters. The following script is one folder above my blend file:
from sys import path
path.append('//../fbx_collection_export.py')
from fbx_collection_export import export

When running it, I get the this error:

ModuleNotFoundError: No module named 'fbx_collection_export'

Q: What am I doing wrong and how can I fix it?
from sys import path
path.append(bpy.path.abspath(&quot;//&quot;)+'/../Scripts')
from fbx_collection_export import export
