How to import text files to a cell array from a folder

Hello,

I know this might be a popular question, but I've tried the proposed solutions in other questions and I couldn't make my code work.

My problem is the following: I have .txt files with electrophysiology recordings. Each file has headerlines, followed by the data (3 column). I have a function that works perfectly opening single files, but I would like to write one that could open all the files in a given folder, and that imports the information to a cell array.

This is my current code:

   function mydata = openFolder(x)

    C = dir(x);
    C = C(~[C.isdir]);

    numfiles = numel(C);
    mydata = cell(1, numfiles);

    for ii = 1:numel(C)
       fid = fopen(C(ii).name, 'w+');
       mydata{ii} = textscan(fid,'%s %s %s', 'headerlines',4);
       fclose(fid);
    end

The code is able to read the files (the fid number is high enough), and mydata cell seems to have the right size (if I am loading a folder with 11 .txt files, mydate is a 1x11 cell array). But when I explore one of the cell arrays contained in myfolder variable, they are empty. There is no data inside.

I would appreciate any help.

dinfo = dir('*.txt');
for K = 1 : length(dinfo)
  thisfilename = dinfo(K).name;  %just the name
  %read the  file data
  %do something with the data
end
