第一次发帖，但长期以来一直是在此站点上查找 VBA 和 SQL 解决方案的粉丝。我有一个 VBA 子例程，旨在查找用户指定的目录中的所有 PDF 文件。该程序对所有子文件夹进行递归并生成如下电子表格：
A 列：完整的文件路径（“C:\Users\Records\NumberOne.pdf”）
B 列：包含文件的文件夹路径（“C:\Users\Records\”）
C列：文件名本身（“NumberOne.pdf”）
到目前为止，程序（下面的代码）可以完美运行。我用它搜索了一个包含超过 50,000 个 PDF 文件的目录，并且每次都成功生成电子表格（在大型目录中，程序的总运行时间通常为 5-10 分钟）。
问题是我想添加 D 列来捕获 PDF 文件的创建日期。我已经用谷歌搜索了这个并为它工作了几个小时，尝试了 FSO.DateCreated 等技术，但没有任何效果。如果 FSO.DateCreated 是我需要的，我不确定将它插入我的子例程中的哪个位置以使其工作。通常我会收到一个错误，即对象不支持该属性或方法。是否有人碰巧知道我可以在哪里为我的程序插入正确的代码以查找每个 PDF 的创建日期并将其放入输出电子表格的 D 列中？
