就是这个脚本：

 @echo off
chcp 65001 >nul
powershell -WindowStyle Hidden -Command "$root = '\\?\' + (Get-Location).ProviderPath; [System.IO.Directory]::EnumerateFiles($root, '*', [System.IO.SearchOption]::AllDirectories) | Where-Object { [System.IO.Path]::GetFileName($_) -eq 'nul' } | ForEach-Object { [System.IO.File]::Delete($_) }"
exit
