Hi, by 'how can I save each of them?!' do you mean saving the contents of the files in one variable? What are the contents of the files?

If you want to store elements (like strings) that are not the same size you can use cells.
A = {'abc', 'defg', 'hijklmnop', 123, [4,5,6,7,8], false}
A =
'abc' 'defg' 'hijklmnop' [123] [1x5 double] [0]
So if you want to go through a bunch of files and put their content in a cell you can do it this way (pseudo code)
my_list_of_files= {'file1','file2', 'file3'}
my_array = {};
for i=1:length(my_list_of_files)
my_array{i} = read(my_list_of_files{i});
end

"I don't know how to insert them in a cell array..."
N = number of files
C = cell(1,N);
for k = 1:N
... import your data
YourData = ... whatever
C{k} = YourData; % store your data in a cell array
end
"...plus my column data size aren't same as each other.during reading each file"
Is irrelevant if you are using a cell array.
