file - VBS 首先复制最大的文件

Question

今天早上我一直在努力解决一项我不敢相信以前没有人想做的任务 - 将文件、子目录和所有文件的目录复制到另一个位置，但严格复制最大的首先是文件。为什么？因为，据我所见，这将有助于停止将大文件复制到 USB 闪存中，因为它似乎复制文件然后移动它的方式，留下文件大小的间隙。更大的文件无法填补这个空白，所以自己制作。ETc 等最终结果 - 最大的第一个应该希望意味着 1 个间隙用于所有副本，并且生成的文件都在它之后连续排列。我对碎片文件并不执着，而是在 USB 上获取连续文件，如 iso/images。

所以这就是我到目前为止所得到的 - 需要解决的 2 个问题： 1 - 如果目标路径不存在，则只在目标路径上创建 1 级目录 - 我需要它来尽可能多地创建不存在的目录然而 2 - 当第一个副本开始时，它说“没有足够的空间”，即使这个设备上还剩下 30g 来复制一个 4g 的文件。

欢迎大家踊跃投稿！

我现在已经使用下面建议的代码工作了，并且在这个新脚本中进行了一些错误检查和修复。但是我仍然遇到无法复制到 USB 的问题。我已将路径更改为 C 驱动器并且它可以工作 - 所以我只能假设这是因为最大的文件是 4.6g，而 USB 是 FAT32，理论上限制为 4G 文件（Windows 可以复制到它吗？）

好的！我现在已经对两种风格的脚本进行了排序，并添加了一些捕获和通知消息 - 我忍不住;）我还发现我可以使用 ghost explorer 调整我的 ghost 图像的大小，使它们 <4g 以便现在它们复制到 USB - 耶！所有这一切的唯一缺点是某些文件仍然碎片化，但是嘿 - 这些脚本仍然可以按预期完美运行 :) 选择！
