　　Tried it, it seems that it can only split text files. Splitting other files may damage the file structure, making the file unusable.

You replied to the wrong post upstairs? Hehe^_^

Correct usage:
for /f %%i in ('devcon findall usb* ^|find /i "usb mass storage"') do devcon remove "@%%i"
After removing the USB flash drive, unplug it, then execute devcon rescan
Or you don't need to execute devcon rescan, the next time you insert it, it will automatically rescan the USB flash drive

I tried several times last night. The correct method:
Execute "for /f %%i in ('devcon findall usb* ^|find /i "usb mass storage"') do devcon remove "@%%i" to remove the USB flash drive, then unplug the USB flash drive, and then execute "devcon rescan" to scan new hardware. If executed together, the USB flash drive is not unplugged in time and is scanned out; of course, you can also not execute "devcon rescan"

ZH159. I executed the command you said. The result is as shown in the following picture:

In the command line, when executing the for statement, %%i should be changed to %i, which is different from %%i in batch scripts.

Which senior can just write a command for me. I'll modify this. Can't remove that. Just can't.

ZH159 big shot

"You just need to remove that line where devcon rescan is added in your bat. Because this is for rescanning. ReScanUsb~ You just need to delete that line and there's no need for rescan. Also, you can just reply directly instead of sending me a private message."

Do you mean to remove the letters devcon rescan? Keep the rest unchanged. I tried but it still doesn't work. Is there any problem with spaces? Can you send it again? Please help, kind person

．．．．．．
It should be no problem. You just want to delete the device, so in that P processing file, as long as there is this line:

for /f %%i in ('devcon findall usb* ^|find /i "usb mass storage"') do devcon remove "@%%i"

devcon rescan is to rescan the device, so you don't need to add it.

I think I explained it very detailedly~
