China DOS Union

Requirement: There are two files, D:\35.RMVB and D:\35OK.RMVB. Determine whether the sizes of these two files are the same. If the sizes are the same, delete D:\35.RMVB.
Please give help, little brother is very grateful.

The following is the demonstration code. If it works, just replace the echo statement with the del statement:

@echo off

for %%i in (D:\35.RMVB D:\35OK.RMVB) do call set var=%%var%% %%~zi

call :comp_size %var%

pause

goto :eof



:comp_size

if %1 equ %2 echo The file D:\35.RMVB is about to be deleted

goto :eof

Still a bit unclear...

What does `call set var=%%var%% %%i` mean here? I'm a newbie, sorry.

　　There is a small error here, %%i should be written as %%~zi, and the code on floor 2 has been corrected.

　　This sentence means to obtain the byte sizes of the two files and assign them to var.

@echo off
for %%i in (D:\35.RMVB D:\35OK.RMVB) do call set var=%%var%% %%~zi
call :comp_size %var%
pause
goto :eof

:comp_size
if %1 equ %2 del D:\35.RMVB
goto :eof
According to the method you said, a fault occurred during execution. At this time, there should be no del.
I don't know if the moderator has tested it?

Suggest the moderator to translate the code. I'm a beginner. Thanks in advance

I made a mistake, and the test was successful
