Unable to perform assignment due to the different length of sides

[FileName,pathname,d] = uigetfile('*.sp3','Choose the products','MultiSelect','on');
for i=1:2
full_file_name(:,i) = fullfile(pathname,FileName(:,i));
end
full_file_name=char(full_file_name); 
for i=1:2
Str(i,:) = fileread(full_file_name(i,:));
end

Here, when the lenght of first and second Str is not equal, I receive "Unable to perform assignment because the size of the left side is 1-by-35930605 and the size of the right side is 1-by-35909334" error. How I can store multiple Str while the theirs lenght are different?

A cell array could be appropriate here:

Str{i} = fileread(full_file_name(i,:));
