Windows uses a batch file to change the file name (including the serial number) in the specified directory

For pictures downloaded from the Internet, the default name is a relatively long character string composed of many letters and numbers, which is not easy for people to remember and is troublesome to use. As shown below:

The purpose of this article is to write a batch file to rename all files with the extension jpeg in the directory to date plus serial number format. The content of the batch file (assuming the file name is d:\temp\my.bat) is as follows:

@echo off 
setlocal EnableDelayedExpansion
rem setlocal DisableDelayedExpansion 
set a=1
set a=2 & echo !a!
set /a n=1000
for %%i in (D:\Images\temp\*.jpeg) do (
	echo %%i
	set /a n=n+1
	ren %%i 20221118_!n!%%~xi
)

 Double-click the above batch file directly with the mouse (ie "d:\temp\my.bat"). After the program runs, all files in the directory will be renamed, and the result is shown in the figure below.
