(Edited) After finding how to return all images links and names of multiple subfolders in a google sheet, I want them all to be sorted. When it returns what I want in my google sheet, the folders are not sorted in order (my folders names are 0, 1, 2, 3...). And when it returns the images in the folders, they are not sorted by names as well (their names are also 01.png, 02.png...), I can use the google sheet method to sort them alphabetically, but it's a bit too long to do it for every folders, here is what I mean and the script :
Google sheet result
var eps0= [ //not the first folder
//wanting here to sort every lines by image names
