How to read all the .txt files in a folder and convert them to matrixes?

I have a bunch of txt files in a folder (version 1,1.txt; version 1,2.txt; etc.). A sample file is attached. I need to convert the data into a matrix. I came up with the follwoing script. I appreciate your help to get it fixed.

% convert P-E scripts to E-P

 clc, clear, close all;

    Root='C:\Users\ski\CloudStation\Zahra\dissertation\stimuli and documents\methodStimuli\stimuli\english experiment/';
    Drop='C:\Users\ski\CloudStation\Zahra\dissertation\stimuli and documents\methodStimuli\stimuli\farsi experiment/';

% Read

        F = dir('*.txt');
        for ii = 1:length(F)
            fid = fopen(F(ii).name);
            A=readtable(fid);  %read the .dat file but dat data is converted to a table
            B= table2array(fid);    %dat table data is converted to an array. but the resluts are string and cells. 
            Bmtx = str2double(B);    %convert the string , or cell?, to ordinary data matrix. 
            data=Bmtx; 
end

% write the file

            fid = fopen((fid),'wt');   %creating a txt type file.
        for h = 1:size(data,1)
            fprintf(fid,'%g\t',data(h,:));
            fprintf(fid,'\n');

        end
            fclose(fid)

This is a good post to: process a sequence of files

If you have files that do not fit in memory, you can use a tabulartextdatastore

Due to the unique structure of this file, for more granular control on importing your data, you can use 'readtable' with d'etectImportOptions' for your data as follows:

>> opts = detectImportOptions('version 1, 2.txt');
>> opts.Delimiter = '\t';
>> opts.ExtraColumnsRule = 'ignore';
>> opts.VariableNames = {'label', 'mode', 'dur', 'win', 'iti', 'rdB','ldB', 'resp' 'type', 'filename'};
>> opts.VariableTypes = {'double', 'char', 'double', 'double', 'double','double', 'double', 'double', 'double', 'char'};
>> opts.SelectedVariableNames = {'label', 'dur', 'win', 'iti', 'rdB', 'ldB', 'resp', 'type'};
>> opts.DataLines = 5;
>> ans = table2array(readtable('version 1, 2.txt',opts));
