How to concatenate multiple files with 2 cell arrays each into one file in such way as the first cell array from the first file will go to the first column the second to the second column and so on in numerical order using for loop is fine...

Hi, there, I'm relatively inexperienced in matlab, and programming overall. So my code lower on the page may be dumb...
I'm trying to take in multiple files with 2 arrays of numbers each and concatenate all of them into a single file so first cell array from the first file will go into the first column in the new file, the second array from the first file will go into the second column of the new file. The first array from the second file will go into the third column of the new file, the second array of the second file will go into 4th column of the new file and so on...
Trying to think about the solution with for loop, not really works...
Any help is appreciated, thanks.
for i=1:length(Files)
if (i == 1)
tmp = load(Files{i},'-mat');
S(i).data1 = tmp.data1;
S(i).data2 = tmp.data2;
Data1{i} = S(i).data1;
Data1{i+1} = S(i).data2;
else
tmp = load(Files{i},'-mat');
S(i).data1 = tmp.data1;
S(i).data2 = tmp.data2;
Data1{i+1} = S(i).data2;
end

Thanks.
Found a solution, which appears to be simpler than I thought.
for i=1:length(Files)
tmp = load(Files{i},'-mat');
Data = [Data,tmp.data1,tmp.data2];
end

Try this (sample files attachted):
numberOfFiles = numel(dir('*.txt'));
for ii = 1:numberOfFiles
fileName = strcat('file',num2str(ii),'.txt');
A = load(fileName);
B{ii} = A;
end
C = cell2mat(B);
dlmwrite('newFile.txt',C)

RG's answer moved here for consistency:
Thanks.
Tried it for my data, doesn't work:
-----"Warning: Input should be a string, character array, or cell array of character arrays."
and then more errors...
so the data that I'm trying to concatenate is an array of numbers,a column of numbers (maybe I'm confused about specificty of cell array definition in MATLAB...)
I'm loading the files into MATLAB using load with dot indexing form the listbox function (that has a list of file names in certain order) and passes this list of files into pushbutton function, in which each file is suppose to be loaded and from each file I take two number arrays/columns and put it in the new file...

Not sure what files you want me to post, again, those files are huge, most of the information is not relevant, this is not relevant for the question I asked.
I'm able to extract the data that I need - I need for loop to run in such way that this information (columns of numbers will be fully transfered to a single file in an organized fashion...).
Thanks anyway for the attempt to help.

Sorry for the disconnect. The best I can offer you is whatever direction my first solution gives you. Hopefully someone else can help.
