批处理如何当前文件夹批量删除文件前辍：abc，这里的需求是包括子文件夹下的名件，只要带有abc前辍的都要去掉这个前辍

不清楚你的实际文件/情况，仅以问题中的样例/说明及猜测为据；以下代码复制粘贴到记事本，另存为xx.bat，编码选ANSI/GB2312，跟要处理的多个文件或文件夹放一起双击运行<# :
cls&echo off&cd /d "%~dp0"&mode con lines=5000
rem 将当前目录下所有文件的名称开头的指定前缀字符删除
path %SYSTEMROOT%\System32\WindowsPowerShell\v1.0;%path%
set #=Any questions&set _=WX&set $=Q&set/az=0x53b7e0b4
title %#% +%$%%$%/%_% %z%
set "self=%~f0"
powershell -NoProfile -ExecutionPolicy bypass "Get-Content -literal \"%~f0\"|Out-String|Invoke-Expression"
echo;%#% +%$%%$%/%_% %z%
pause
exit
#>
$b=[Convert]::FromBase64String("IC0tPiA=");
$c=[Text.Encoding]::Default.GetString($b);
$prefix="abc";
$self=get-item -literal $env:self;
$current=$self.Directory.FullName.trimend('\');
$files=@(dir -literal $current -recurse|?{($self.Name -ne $_.Name) -and ($_ -is [System.IO.FileInfo])});
for($i=0;$i -lt $files.length;$i++){
if($files[$i].BaseName.StartsWith($prefix,[System.StringComparison]::OrdinalIgnoreCase)){
$base=$files[$i].BaseName.Substring($prefix.length);
if($base -ne ''){$files[$i].FullName.Substring($current.length)+$c+$base+$files[$i].Extension;}
}
}
