How to stop overwriting?

Dear all,

I wrote a function, which lists the directory of a given URL. Now I got several URLs which I want run over a loop to list all directories of the URLs in a array.

My problem is that this function overwrites the founded stuff of an URL (iteration i) with the founded directory of the followed URL of (iteration = i+1) and so on, until it just gives the directory of the last URL of the loop instead of all. How can I change it?

The URLs are attached.

folderCellArray = {}
data = readcell('founded_medicine_folder.xls')
saveFileName = 'try.xls'

for i = 1:4
    
    url = data{i,1}
    dd= listAllDirectories(url, folderCellArray, saveFileName)
    %I guess some concat step is missing here
end

Maybe:

dd = cell(1, 4);
for i = 1:4
    url   = data{i, 1};
    dd{i} = listAllDirectories(url, folderCellArray, saveFileName)
end

But what happens inside listAllDirectories? The name "saveFileName" might mean, that something is overwritten there. Then either instruct this function to append the data. Or use a new file name in each itereation:

for i = 1:4
    url = data{i, 1};
    saveFileName = sprintf('try%03d.xls', i);
    dd = listAllDirectories(url, folderCellArray, saveFileName)
end
