以 “_” “A” “B”结尾的为旧文档？
好你看明白了点，是比较后两位字符大小的问题。

未做优化，文件夹名自己看情况改。用临时文件方法，少动脑细胞：

@echo off & setlocal EnableDelayedExpansion
pushd "%~dp0"
MD 旧图纸备份>nul 2>nul
MD tmp>nul 2>nul
for /f "delims=" %%a in ('dir/a-d/b *.pdf') do (
	set "str=%%~na" & set "str=!str:~0,-2!"
	md tmp\!str!\ >nul 2>nul
	cd.>tmp\!str!\%%a
)
for /d %%a in ("tmp\*") do (
	call :NEW "%%a" old
	for /f "delims=" %%e in ('dir/a-d/b *.pdf') do (
		set "name=%%~ne"
		if /i "!name:~0,-2!"=="%%~nxa" if "%%e" neq "!old!" move /y "%%e" "旧图纸备份\"
	)
)
rd /q /s tmp>nul 2>nul
pause & exit
:NEW
for /f "delims=" %%a in ('dir/a-d/b "%~1\*" ^|sort /r') do (set "%2=%%a" & goto :eof )
