Get the file creator / owner attribute in Java

I'm trying to read the file list and find the user who created the file With the * Nix system, you can perform similar operations

Map<String,Object> attrs = Files.readAttributes(Paths.get(filename),"posix:*");

However, when trying it on a Windows system, I received an error because windows could not access POSIX properties You can get general (non POSIX) attributes by doing the following:

attrs = Files.readAttributes(Paths.get(filename),"*");

However, the creator of the file is not included in the list

Is there any way to find out who creates files in Java programs running on windows?

Solution

I believe you can use files getOwner(Path,LinkOption...) To get the current owner (or possibly the creator)

Path path = Paths.get("c:\\path\\to\\file.ext");
try {
    UserPrincipal owner = Files.getOwner(path,LinkOption.nofollow_LINKS);
    String username = owner.getName();
} catch (IOException e) {
    e.printStackTrace();
}
