Python: Own package not recognized

I have an issue where I dont get the solution. I also look here in stackoverflow.com, tried different solutions but nothing helps.

My project struct looks like this:

-MyFolder
----MySubFolder
------MySubFolder.py
------__init__.py
----MyFolder.py
----__init__.py

To be clear. MyFolder.py and his init.py are below MyFolder and above MySubFolder.

In a different project, I import MyFolder, but PyCharm doesn´t recognized MyFolder as a Package. MyFolder is part of PYTHONPATH, so it should be found.

In the init.py inside MyFolder, it looks like:

import os
import sys
fpath = os.path.join(os.path.dirname(__file__))
sys.path.append(fpath)

from MyFolder import *

and in MySubFolder

import os
import sys
fpath = os.path.join(os.path.dirname(__file__))
sys.path.append(fpath)

from MySubFolder import *

But when I do

from MyFolder.MyFolder import *

then it working. But my goal is only to import MyFolder
