you can make new folders and just set them all to have the same parent folder! the sub folders serve no purpose except to hold characters, all of the code and links go to the other one with the same name

for the folder i see you've tried it on, make sure the a href links to the folder the code is in, aka https://toyhou.se/Flamingo_mist/characters/folder:3911871

also fyi, you only need the sub folder with the same name if there are no other subfolders there. so your tree tops folder does not need a tree tops sub folder
