How do I check the user inputted name in edit box is a folder or not ?

I want a user to input the name. Then check that named folder exists or not. If exists then show warning message else create a folder of that name.

I have written a code but it is showing me some error

a = get(handles.Name,'String'); 
  if isempty(a) 

        errordlg('ENTER FIELDS PROPERLY','Error')

        return

    else
        if exist('C:\Users\naomi\Desktop\',a)
           warndlg('EXIST');
           return
        else
            mkdir('C:\Users\naomi\Desktop\'a)
        end 
    end

Error using exist The optional second input to exist must be 'var', 'builtin', 'class', 'dir' or 'file'.

projectdir = 'C:\Users\naomi\Desktop';

a = get(handles.Name,'String'); 
if isempty(a) 
      errordlg('ENTER FIELDS PROPERLY','Error')
      return
end
targetdir = fullfile( projectdir, a );
if exist(targetdir, 'dir')
   warndlg('EXIST');
   return
else
   mkdir(targetdir)
end

Have you considered using uigetdir() ?
