用bat脚本写一个遍历文件夹随机复制一个文件到另一个文件夹并重新命名复制完成后删除原文件

@echo off setlocal enabledelayedexpansion

set source_path=C:\source_folder set target_path=C:\target_folder

set /a count=0

for /r "%source_path%" %%f in (*) do ( set /a count+=1 set "file=%%f" )

set /a random_num=%random% %% %count% + 1

set /a current_num=0

for /r "%source_path%" %%f in (*) do ( set /a current_num+=1 if !current_num! equ %random_num% ( set "file=%%f" set "file_name=!file:%source_path%=%target_path%!" set "file_name=!file_name:=_!" copy "!file!" "!file_name!" del "!file!" exit /b ) )
