I really don't understand this, hope some experts can explain it.
In addition, limited by the fact that the maximum value of numbers that batch processing can correctly handle is 65536*65536/2-1, that is 2147483647,
so when the file is too large, this batch processing can't display correctly either.

Small-capacity files seem to be correct, but large-capacity files are a bit worse. Still, thank you.

The reason has been found. Reminded by 9527, it turned out that it was because the parameter /-c was forgotten to be used. It is used to remove the delimiter, so the code is changed to

@echo off md h:\5 xcopy/s/e/q i:\*.* h:\5>nul&cd/d h:\5 if exist *.bak del *.bak for /f "tokens=1-4 delims= " %%i in ('dir/a/s/-c ^|find "文件"') do set a=%%i&set b=%%j&(if not "%%k"=="" set/a size=%%k/1048576) echo %a%%b% %size%MB>c:\1.txt for /f "skip=2 delims=" %%i in ('tree /f h:\5') do @echo. %%i>>c:\1.txt start c:\1.txt

Now it's displayed correctly, thanks a lot to the two brothers ccwan and 9527!
