In python 3 running on Windows, how do I get the owner of a file

To get the owner of a file in Python 3 running on Windows, you can use the ctypes
module to interact with the Windows API. Here's an example:
pythonimport ctypes
from ctypes import wintypes
def get_file_owner(file_path):
# Convert the file path to a wide character string
file_path_wide = ctypes.wstring_at(file_path.encode('utf-16-le'))
# Get the owner SID (Security Identifier) of the file
sid = ctypes.create_string_buffer(1024)
sid_size = ctypes.c_ulong(ctypes.sizeof(sid))
domain = ctypes.create_unicode_buffer(1024)
domain_size = ctypes.c_ulong(ctypes.sizeof(domain))
sid_name_use = wintypes.DWORD()
success = ctypes.windll.advapi32.LookupAccountNameW(
None, file_path_wide, sid, ctypes.byref(sid_size),
domain, ctypes.byref(domain_size), ctypes.byref(sid_name_use)
)
if success:
# Convert the SID to a string format
sid_string = ctypes.wstring_at(sid, sid_size.value)
domain_string = ctypes.wstring_at(domain, domain_size.value)
return f"{domain_string}\\{sid_string}"
else:
return None
# Example usage
file_path = r"C:\path\to\file.txt"
owner = get_file_owner(file_path)
if owner:
print(f"Owner: {owner}")
else:
print("Unable to retrieve file owner")
In this example, the get_file_owner
function accepts a file path and uses the LookupAccountNameW
function from the Windows API to retrieve the owner SID and domain of the file. It then converts the SID and domain to string format and returns the result.
Make sure to adjust the file_path
variable to the path of the file you want to retrieve the owner for.
Note that this solution is specific to Windows and relies on the Windows API. It may not work on other operating systems. Additionally, the code assumes that you have appropriate permissions to access the file and retrieve its owner information.
