【问题描述】：
我的计算机上有一个软件，当我从中运行报告时，它会自动输出一个包含 4 个 csv 文件的文件夹。每次我运行报告时，我都会得到一个包含 4 个新文件的新文件夹。这些文件夹和文件会自动与我在 GDrive 中的一个文件夹同步。我设置了以下脚本来获取 4 个电子表格，并在文件上传后将它们合并到同一文件夹中的 1 个新工作表中。我计划设置脚本以在基于时间的事件上运行，它遍历其所有子文件夹并将文件组合到 1 个文件中。
我试图弄清楚如何确保是否已经为该文件夹生成了一个文件，它会跳过该文件夹。我有以下代码，但它不起作用，并且仍在生成多个文件。我最初的想法是计算文件夹中文件的基本数量，如果大于该数量，则不应运行脚本。我相信我的 if 语句代码有错误。

为了便于阅读，我插入了几条断线以避免水平滚动条。还删除了由于 Google Apps 脚本不在此处运行而被截断的 Javascript/HTML/CSS。
