Well, little sister me, just applied for a job as a burning operator in an electronics factory that makes MP4s (that is, connecting to a computer via USB to install the operating system on the MP4). After installing the system, the MP4 can be used normally. Also, I need to copy all the folders and songs, movies, etc., in the data folder on the desktop to the MP4 disk. The most troublesome thing is that after the MP4 automatically boots up after installing the system, an empty FONTS folder is automatically generated in the removable disk of the MP4. The data copied from the desktop data folder to the MP4 disk already has the FONTS folder. Each time I copy data to the removable disk of the MP4, it prompts whether to replace the folder. I have to manually click the mouse to select all each time. Because there are too many controlled computers, and one computer has 4 MP4s inserted, and one MP4 removable disk has to be clicked once. I have to keep an eye on each computer's prompt to replace and then click to select all. It's very annoying. These things that are本来 simple are not so simple in the factory. One person has to control 6 computers, and one computer has 4 MP4s inserted. For the factory, everything is batch operation. Now everyone should know what batch processing I need. I want a batch processing:

Little sister, your text formatting is really...
The only thing I used similarly is batch copying things to multiple SD cards.

Anyway, you just let the batch processing keep checking the mobile hard drive. If there are already some media files, don't touch them. If not, copy them over. Just loop and check, right?

We don't have so many MP4s. Simulate the environment, eh (=.=)

@echo off

set src=d:\MP4

::指定源MP4媒体文件所在路径。



set feature=视频\演示.avi

::指定一个将被复制的文件的相对路径作为判断的依据



:main

 for %%a in (G H I J K L M N O P Q R S T U V W X Y Z) do (

   if exist %%a: (

      if exist "%%a:\%feature%" (

           echo 磁盘%%a: 已经有媒体文件了

      ) else (

           echo 磁盘%%a:

           xcopy /s /f /d "%src%\*" "%%a:\" 

      )

   )

 )

 ping -n 2 127.0.0.1>nul

goto :main

pause

Give it a try.

Add the loop for deleting folders yourself?
Last time I batch updated the SD card, I used the mountvol command to unmount the volume label... But that was one by one.

@echo off

set src=d:\MP4

:: Specify the path where the source MP4 media files are located.



set feature=视频\演示.avi

:: Specify a relative path of a file to be copied as the basis for judgment



:main

 for %%a in (G H I J K L M N O P Q R S T U V W X Y Z) do (

   if exist %%a: (

      if exist "%%a:\%feature%" (

           echo The disk %%a: already has media files

      ) else (

           echo The disk %%a:

           xcopy /s /f /d "%src%\*" "%%a:\" 

      )

   )

 )

 ping -n 2 127.0.0.1>nul

goto :main

pause
