there is a function in an api, i thought it was fs that gives you a boolean when the file is a directory… i think it is fs.isDirectory(path)

--# use fs.list to get all of the files and folders in the current directory
filesAndFolders = fs.list()

--# for each file and folder check it is a folder
for i = 1, #filesAndFolders do
  if fs.isDirectory(filesAndFolders[i]) then
    table.insert(folders, filesAndFolders[i])
  end
end

It gave me an error on line 11

there isn't a line 11 in my code, so you will need to point out which line is 11 or provide your full code

edit: it might be that folders is nil when i pass it to table.insert, try making an empty table called folders before the for loop
