使用robocopy时如何跳过现有和/或相同大小的文件 [英] How to skip existing and/or same size files when using robocopy

问题描述

我有此代码:

@echo on
set source="R:\Contracts\"
set destination="R:\Contracts\Sites"

::Not sure if this is needed
::It guarantees you have a canonical path (standard form)
for %%F in (%destination%) do set destination="%%~fF"

for /r %source% %%F in (.) do if "%%~fF" neq %destination% ROBOCOPY "%%F" %destination% *.srt *.pdf *.mp4 *.jpg /COPYALL /R:0

Pause

如果文件存在，我不确定上面的代码是否包含"SKIP命令"，如果文件大小相同，则跳过吗?

I am not sure if the code above has "SKIP commands" if file exists / or skip if file is the same size?

推荐答案

您要排除相同大小的文件还是未更改的文件?如果是后者，请使用RoboCopy中的/XO开关排除比复制过来的文件更旧的文件.

Do you want to exclude files of the same size, or files that haven't changed? If it's the latter, use the /XO switch in RoboCopy to exclude files that are older than those they're being copied over.

RoboCopy "%%F" %destination% *.srt *.pdf *.mp4 *.jpg /COPYALL /XO /R:0
