这是一个批处理脚本，可满足您的需要。
您没有提到在重复的path \ filename.pdf（来自不同驱动器）的情况下想要发生的情况。
因此，如果发现重复，我要做的是在文件名的末尾添加一个唯一的数字。
例如，如果您有以下文件：
C:\Dir\A.pdf
C:\Dir\B.pdf
C:\Dir\B-1.pdf
C:\Dir\B-2.pdf
C:\Dir\C.pdf
C:\Dir\C-1.pdf
F:\Dir\A.pdf
F:\Dir\B.pdf
F:\Dir\C.pdf
并且您的目标路径是：
"D:\Test"
然后脚本将复制：
C:\Dir\A.pdf -> D:\Test\Dir\A.pdf
C:\Dir\B.pdf -> D:\Test\Dir\B.pdf
C:\Dir\B-1.pdf -> D:\Test\Dir\B-1.pdf
C:\Dir\B-2.pdf -> D:\Test\Dir\B-2.pdf
C:\Dir\C.pdf -> D:\Test\Dir\C.pdf
C:\Dir\C-1.pdf -> D:\Test\Dir\C-1.pdf
F:\Dir\A.pdf -> D:\Test\Dir\A-1.pdf
F:\Dir\B.pdf -> D:\Test\Dir\B-3.pdf
F:\Dir\C.pdf -> D:\Test\Dir\C-2.pdf
最初，脚本将仅显示要复制的文件。一旦确定将正确的文件复制到正确的路径，请对脚本进行此更改...
查找此行（在顶部附近）：
set zzlive=0
并将其更改为：
set zzlive=1
此外，您会发现一些行，例如：
set zztarget1="C:\*%zzftype%"
set zztarget2="F:\*%zzftype%"
set zztarget3="D:\*%zzftype%"
根据需要添加任意数量的“文件夹” ...依次编号。
脚本运行时，这些行将“扩展”为：
set zztarget1="C:\*.pdf"
set zztarget2="F:\*.pdf"
set zztarget3="D:\*.pdf"
最后，查找如下所示的行：
rem Create .zip
在该行下面，添加命令来创建“ .zip”文件，但是要执行此操作，具体取决于要将“ .zip”文件放置在何处以及所需的其他“ .zip”文件选项。如果您需要帮助，请告诉我一些细节，我会为您提供帮助。
如果您需要更多信息，或者需要脚本以其他方式工作，请告诉我。
这是脚本：
@echo off
rem set "live" (or "test"). 0=test, 1=live
set zzlive=0
rem set "Test" folder
set "zzhold=D:\test"
rem set File type to process
set "zzftype=.pdf"
rem set targets
set zztarget1="C:\*%zzftype%"
set zztarget2="F:\*%zzftype%"
set zztarget3="G:\*%zzftype%"
rem set more targets, up to 10 ...
rem set "Subst" drive. Use *ANY* unused drive letter
set "zzsubst=V:"

PDF文件是否在每个驱动器上的特定目录中？还是在整个驱动器中？
