I've seen some files on the FEX that allow you to get creation date / last modified date of a particular file

(See http://www.mathworks.com/matlabcentral/fileexchange/24671)

but does anybody know how to get the name of the "Owner" of a file? (Which is another thing displayed by Windows Explorer so it has to be accessible somehow??)

Here's one way:

fileName = 'test.m';  % Some file you're interested in.
commandString = sprintf('dir %s /Q > owner_of_%s.txt', ...
  fileName, fileName);
system(commandString)
filebrowser; % Optional - Show current folder panel
% Now open the txt file you just created
% and parse it to find the owner.

You can use .NET:

finfo = System.IO.FileInfo(FileName);
dummyAccount = System.Security.Principal.NTAccount('dummy');
Owner = char(finfo.GetAccessControl.GetOwner(GetType(dummyAccount)).Value.ToString);

There must be a more direct method to get the NTAccount type instead of creating a dummy account.

The Windows API methods are not trivial and I hesitate to implement them in a function similar to GetFileTime.

not sure how to accept both your answers? but they both worked (so i accepted Image's and voted for yours??)....thanks for the help!

The .NET method includes the host name also, such that file owners of network drives are identified uniquely. The DIR approach does not handle this and demands for a complicated parsing of a text file.
