"FileNotFoundError" using pathlib after freezing the script

[sirlagg]

As a part of a python application, files in unmapped network drive are accessed. The script runs like a charm when running the .py file, but after freezing it as an .exe file using cx_freeze I am getting the following error:

FileNotFoundError: [WinError 3] The system cannot find the path specified: '\one\random\folder\file.txt'

When running the following line:

sizelist = [float(Path(x).stat().st_size) for x in ListOfFiles]

The file definitely exists. I have noticed that under file properties in Windows, the file path is shown as:

\?\UNC\one\random\folder\file.txt

I have isolated the issue as caused by cx_Freeze. I have frozen the following script in cx_Freeze and pyinstaller:

# encoding: utf-8

from pathlib import Path

folder = input("Folder:")
file_list = []
file_list += list(Path(folder).rglob("**/*.mdf"))
file_list += list(Path(folder).rglob("**/*.mf4"))
file_list += list(Path(folder).rglob("**/*.dat"))
print([(Path(p), Path(p).is_file()) for p in file_list]) # For tracking

x = input("Press enter...")

When frozen with pyinstaller, Path(p).is_file() is True for all files. With cx_Freeze, some obtain True and the ones with the "\?\UNC" start of the path fail.

Is it there a way to solve this issue on cx_Freeze?

Python from python.org or conda? What version?
python -VV

Python from python.org

Python 3.11.3 (tags/v3.11.3:f3909b8, Apr 4 2023, 23:49:59) [MSC v.1934 64 bit (AMD64)]

I cannot reproduce with python 3.11.4
I used the following code:

main.py
    from pathlib import Path
    from pprint import pprint
    #from pyfakefs.fake_filesystem_unittest import Patcher
    #
    folder = "//server/share"
    #patcher = Patcher()
    #patcher.setUp()
    #filesystem = patcher.fs
    #filesystem.add_real_directory("/local/path", target_path=folder)
    file_list = list(Path(folder).rglob("**/*.pdf"))
    #pprint(file_list)
    pprint([(p.as_posix(), p.is_file()) for p in file_list if not p.is_file()])
    #patcher.tearDown()
setup.py
    from cx_Freeze import Executable, setup
    setup(
        name="test",
        version="0.1",
        description="Sample for test with cx_Freeze",
        executables=[Executable("main.py")],
    )

The code in comments using pyfakefs is to be used in a test, if reproducible in a fakefs.
The only issue that I found is in a path accessible via samba that has incurred unicode, but it give a error, not a false positive.

NOTE: folder = "//server/share" can be changed to folder = "\\server\share" and the result is the same.

Release 6.15.3 is out!

Can you give me feedback?
Can I close the issue?

Hi, I have upgraded to the latest version and unfortunately the issue persists...

[marcelotduarte]

Can you reproduce the error with my test code in the previous comment?

[sirlagg]

When running main.exe, it returns [].

When running main.exe with all lines uncommented, it returns this error:

FileNotFoundError: [Errno 2] No such file or directory in the fake filesystem: '/local/path'

Unfortunately, the behaviour is the same when running both the .exe and the .py versions.
