Hi,
you need something like this (adapt it to your path and folders)
% Path of the main folder : Rotation
yourpath = 'C:\Users\YourName\Documents\MATLAB\Rotation';
% Get all the subfolders
ContentInFold = dir(yourpath);
SubFold = ContentInFold([ContentInFold.isdir]); % keep only the directories
% Loop on each folder
MyData = [];
for i = 3:length(SubFold) % start at 3 to skip . and ..
    filetoread = fullfile(yourpath,SubFold(i).name,'FX.txt');
    % then type your code to read the text files and store in one variable
    fileID = fopen(filetoread);
    MyData{end+1} = textscan(fileID,'%s\n'); % the format depends of your files
    fclose(fileID);
end
