先测试,后投产,防止丢文件.我觉得分割后应该删除源文件的,否则500G变成了1TB,太占用磁盘.但 删除文件很危险.
Q1- @echo off
- set "list=.\清单.txt"
- set "dir0=C:\D\Test\ps1\要处理的文件夹"
-
- for /f "usebackq tokens=1* delims=+" %%A in ("%list%") do set "?%%~A=%%~B"
- for /f "delims=" %%A in ('dir /a-d-h /b /s "%dir0%"') do (
- if defined ?%%~nA (
- setlocal enabledelayedexpansion
- for %%B in ("!?%%~nA!") do (
- endlocal
- ren "%%~fA" "%%~B%%~xA"
- )
- )
- )
- for /f "delims=" %%A in ('dir /ad-h /b /s "%dir0%"^|sort /r') do (
- if defined ?%%~nxA (
- setlocal enabledelayedexpansion
- for %%B in ("!?%%~nxA!") do (
- endlocal
- ren "%%~fA" "%%~B"
- )
- )
- )
-
- pause
复制代码 Q2- @echo off
- set "file=文件夹名"
- set "dir0=C:\D\Test\ps1\要处理的文件夹"
-
- for /f "delims=" %%A in ('dir /ad-h /b /s "%dir0%"^|sort /r') do (
- if /i "%%~nxA"=="%file%" (
- move "%%~fA\*" "%%~dpA"
- )
- )

复制代码 Q3 合并- @echo off
