MATLAB: How to fix this code to copy text from a number of text files to a bunch of other text files

copyingdata processingdirectorytext file

I have a number of text files in a directory. I want to copy the contents of each of these text files into brand new text files except I do not want to copy the first 4 lines. For this I have written this code but it is not working. Can you help me fix this?
files = dir('*.TXT')
N = numel(files)
count = 0;
for i = 1:N
  fid1 = files(i).name
  disp(fid1)
  a = fopen(fid1,'r')
  file_name = [sprintf('%1.0f',i) '.txt'];
  fopen(file_name,'w+');
  for K = 1:4
    inline = fgetl(a)
  end
  while ischar(inline)
    inline = fgetl(a)
    fprintf(file_name,'%s\n\r',inline)
  end
  fclose('all')
end

Best Answer

for i = 1:length(files)
  disp(fid1)
  fidI = fopen(files(i).name,'r');
  file_name = [sprintf('%1.0f',i) '.txt'];  % would recommend use a more descriptive name
  fidO=fopen(file_name,'w+');               % you didn't save the file handle...
  for K = 1:4, inline=fgetl(a); end         % skip the four records
  while ischar(inline)
    inline = fgets(a);                      % get line, include \n
    fprintf(fidO,'%s',inline)               % write output; \n is in string by dint of fgets
  end
  fclose('all')
end
