get all the files in the path in a list?

[snippsat]

what do I need to change \ do ?

Not all system take pathlib object,then need to convert to normal string(str object).
Use fspath for this as is made just for this task.

from pathlib import Path
from os import fspath

dest = r'G:\div_code\all_files'
for path in Path(dest).rglob('*'):
    if path.is_file():
        print(fspath(path))

Use type() if you unsure what object used.

from pathlib import Path
from os import fspath

dest = r'G:\div_code\all_files'
for path in Path(dest).rglob('*'):
    if path.is_file():
        print(type(fspath(path)))

Output:
<class 'str'>
<class 'str'>
<class 'str'>
<class 'str'>

def upload_script(routerIP, File_Name_To_Upload):
    UploadOk = "Problem"
    ftp = FTP(routerIP, timeout=60)
    try:
        ftp.login(user=username, passwd=password)
    except error_perm as msg:
        print(f"FTP error: {msg}")
        return "Wrong User or Password"
    except Exception as e1:
        print(e1)
        print("Error in FTP Login!")
        return "Unknown Error"
    else:
 try:
            ftp.storbinary('STOR ' + nameOnRouter, open(filename, 'rb'))
            UploadOk = "OK"
            return "FTP success"
        except Exception as e:
            print('my error')
            print(e)
            UploadOk = "Problem"
            return "FTP Error " + str(e)
        finally:
            print('done with  ' + nameOnRouter + " status " + UploadOk)

this is my fucntion that should read the files and upload them using FTP

To put together i would do it like this.
So a own function that yield files that paths now convert to strings

from pathlib import Path
from os import fspath

def read_files(path_os):
    for path in Path(path_os).rglob('*'):
        if path.is_file():
            yield fspath(path)

def upload_script(file_upload):
    for file in file_upload:
        print(file)

    '''UploadOk = "Problem"
    ftp = FTP(routerIP, timeout=60)
    try:
        ftp.login(user=username, passwd=password)
    except error_perm as msg:
        print(f"FTP error: {msg}")
        return "Wrong User or Password"
    except Exception as e1:
        print(e1)
        print("Error in FTP Login!")
        return "Unknown Error"
    else:
        try:
            ftp.storbinary('STOR ' + nameOnRouter, open(filename, 'rb'))
            UploadOk = "OK"
            return "FTP success"
        except Exception as e:
            print('my error')
            print(e)
            UploadOk = "Problem"
            return "FTP Error " + str(e)
        finally:
            print('done with  ' + nameOnRouter + " status " + UploadOk)'''

if __name__ == '__main__':
    path_os = r'G:\div_code\all_files'
    path_os = read_files(path_os)
    upload_script(path_os)

Output:
G:\div_code\all_files\all_file_req.py
G:\div_code\all_files\Nytt Adobe Photoshop Image 22.psd
G:\div_code\all_files\foo\Articles.csv
G:\div_code\all_files\Ny mappe\Nytt tekstdokument.txt

Try to not use CamelCase in Python write it like this.

UploadOk # No
upload_ok # yes

Look into f-string.

# No
print('done with  ' + nameOnRouter + " status " + UploadOk)

# Yes
print(f'done with {name_on_router} status {upload_ok}')

I understand
and I have foudn the problem , like you suggested
I needed to change to this

Upload_Status = upload_script(ip, str(test_file))

make the 'file' a string and not a path

Thank you ,
