How can I delete a specified folder in Lua?

You can use the os.remove function in Lua to delete a specific folder. Here is an example code:

-- 删除指定文件夹及其内容
function deleteFolder(directory)
    local cmd = string.format("rm -rf %s", directory)
    os.execute(cmd)
end

-- 调用函数删除文件夹
deleteFolder("path/to/folder")

Please note that this method involves deleting a folder by executing shell commands, so make sure that the environment running the Lua code has permission to execute shell commands. Also, be cautious and ensure that the folder you are deleting is the correct one to avoid deleting important files by mistake.
