fileread txt file problem

Greeting everyone, I want to read multiple text file and process it with my script and save it with the same name, but I got error in fileread, can anyone help me?

clc;clear all; close all;
format long g;

% Specify the folder where the files live.
myFolder = 'E:\Data\';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isfolder(myFolder)
    errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
    uiwait(warndlg(errorMessage));
    myFolder = uigetdir(); % Ask for a new one.
    if myFolder == 0
         % User clicked Cancel
         return;
    end
end
Allfile = fullfile(myFolder, '*.txt'); 
List = dir(Allfile);
for k = 1 : length(List)
    sites = List(k).name;
     content=fileread(sites);
     data=textscan(content,'%f%f%f%f[^\n\r]') ;
     data=data{1};
%    sum up dryz+wetz in txt file
    odd_rows = data(1:2:end,3);
even_rows = data(2:2:end,3);
ztd = odd_rows + even_rows;
%  standard deviation values
 stdev = data(1:1:end,4);
newdata = [ztd stdev];

    %save data
save([ '.txt'],'newdata','-ascii');
end

Consider looking into readtable or readmatrix instead of textscan.

% if you want column 5
format long g
file = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1045490/VMF1.BAKO.txt';
data = readtable(file,'TextType','string')

data = 578×5 table
      Var1       Var2          Var3           Var4              Var5

% if you don't
num = readmatrix(file);
num(:,end)=[]

num = 578×4
