Lua/Killa recursive file tree building

-- Lua:
function love.load()
    filesString = recursiveEnumerate("", "")
end

-- This function will return a string filetree of all files
-- in the folder and files in all subfolders
function recursiveEnumerate(folder, fileTree)
    local lfs = love.filesystem
    local filesTable = lfs.enumerate(folder)
    for i,v in ipairs(filesTable) do
        local file = folder.."/"..v
        if lfs.isFile(file) then
            fileTree = fileTree.."\n"..file
        elseif lfs.isDirectory(file) then
            fileTree = fileTree.."\n"..file.." (DIR)"
            fileTree = recursiveEnumerate(file, fileTree)
        end
    end
    return fileTree
end

function love.draw()
    love.graphics.print(filesString, 0, 0)
end

// Kia:
