Question

简介：我有15个Nirsoft.com免费实用程序，我下载到Windows文件夹（＆＃34;源文件夹＆＃34;），以及Nirsoft网页的PDF副本我下载了该实用程序。我下面的python脚本旨在为源文件夹中的每个Nirsoft实用程序的源文件夹中创建一个子目录。然后该脚本应该移动到每个新子目录，属于该子目录的压缩实用程序，以及我从中下载该实用程序的Nirsoft网页的PDF副本。

我的脚本很好地复制了压缩的实用程序。但是，我下载该实用程序的Nirsoft网页的PDF副本无法正确复制。所有子目录中的PDF副本都是损坏的，并且神秘地每个PDF副本与该子目录中的压缩实用程序具有相同的字节数。

详细说明：对于每个实用程序，我都下载到源文件夹中： 1. Nirsoft实用程序，和 2.关于该实用程序的Nirsoft页面的PDF副本。

在我的剧本中，＆＃34; utils_all_ls＆＃34;是一个列表列表。＆＃34; utils_all_ls＆＃34;中的每个列表（＆＃34; util_ls＆＃34;）是一个包含以下内容的列表：

要创建的子目录的名称;
实用程序的描述（我稍后在创建按钮菜单时使用）;
关于该实用程序的Nirsoft页面的PDF副本;
从该页面下载的压缩Nirsoft实用程序。

下面的python脚本会创建每个util_ls [0]中命名的子目录。我的脚本确实成功地将每个子目录复制到util_ls [4]的一个很好的副本，这是压缩的Nirsoft实用程序。但是关于该实用程序的Nirsoft页面的PDF副本总是损坏的，并且PDF文件总是与该子目录中的压缩实用程序具有相同的字节数。

我无法弄清楚PDF文件（1）总是与压缩实用程序具有相同的字节数，以及（2）是否已损坏。

这是我的剧本：

shutil.copy（old_file，nu_file）莫名其妙地制作了PDF文件的损坏副本
