how to get UNC path for mapped drive path

I've got x:\path\filename.ext. I want to resolve this to \\MyUnc\Network\path\filename.ext. Any thoughts on how to do this programatically? Thanks.

If on Windows, you can use system('net use'). I use the following function in one of my codes. I'm sure there is a more efficient way to code this but this works for me.

function MappedPath = findMappedDrive(DriveLetter)
% DriveLetter is just the letter that represents the drive without a
% colon, type char.
            DriveLetter = [DriveLetter ':'];
            system('net use >netuseRun.txt')
            netuseOpen = fopen('netuseRun.txt');
            tScan = textscan(netuseOpen,'%s','Delimiter','\n');
            fclose(netuseOpen);
            delete('netuseRun.txt');
            str = string(tScan{:});
            locate = contains(str,DriveLetter);
            locatemd = strfind(str(locate),'\\');
            conv = char(str(locate));
            MappedPath = strtrim(conv(locatemd:end));
end

Sometimes there may be stuff that gets added at the end of the MappedPath like 'Windows Mapped Drive' so you may want to make a check using exist(MappedPath,'dir'). Hope this helps.
