How to save data of each folders in cell array?

I have four folders r1, r2, r3 and r4. I used for loop for each folders and read files and store data using if statement inside the for loop. But when script for r2 folder, it overwrites the first stored data in a cell array. How do I create different cell array for each folders so that I can store data of each folder in each cell array?

output = cell(subfold_idx,6); this is what i used to define cell? each subfold_idx is in for loop so in 2nd loop the data overwrites. I need to defined cell for each folder.
