I have a project in which a app loads and saves data into sub folders (its a GUI editor), and the script for loading the pickle file and using the data gives an error message ->

Traceback (most recent call last):
  File "d:ProjectsPyEngineTestProjectmain.py", line 12, in <module>
    objects = load_data("objects.pkl")
              ^^^^^^^^^^^^^^^^^^^^^^^^
  File "d:ProjectsPyEngineTestProjectengineFunctions.py", line 12, in load_data
    with open(path, "rb") as file:
         ^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'objects.pkl'

The file structure is ->

Workspace Folder
    main.py
    other python files
    Sub Folder
        main.py
        other python files
        objects.pkl

The sub folder main.py file is able to load properly when subfolder is not in workspace folder,
it does work if I also specify the sub folder name when giving the path, but then it doesn’t work outside of the workspace folder.

Here is a MRE-

file structure ->

Workspace Folder
   main.py
   folder
      main.py

main.py ->

import pickle

class RandomObject:
    def __init__(self) -> None:
        self.name = "Random Object"


def save_data(data, path):
    with open(path, "wb") as file:
        pickle.dump(data, file)
        file.close()

def load_data(path):
    with open(path, "rb") as file:
        data = pickle.load(file)
        file.close()
    return data

data = RandomObject()
save_data(data, "folder/data.pkl")
data = load_data("folder/data.pkl")
print(data.name)

folder/main.py ->

import pickle

class RandomObject:
    def __init__(self) -> None:
        self.name = "Random Object"


def save_data(data, path):
    with open(path, "wb") as file:
        pickle.dump(data, file)
        file.close()

def load_data(path):
    with open(path, "rb") as file:
        data = pickle.load(file)
        file.close()
    return data

data = load_data("data.pkl")
print(data.name)
