PowerShell：使用带括号的 -replace 不起作用

在下面的脚本中，由于方括号的原因，该行$comparisonFile=Get-Item ... \E")不会替换文件$_。如何才能有效地替换文件名中的文本？Q:\Backup Comparison\E\Files\file[1].txt

get-childitem -file -recurse | ForEach-Object {

    #file is: Q:\Backup Comparison\E\Files\file[1].txt

    $comparisonFile=Get-Item ($_.FullName -replace 'Q:\\Backup Comparison\\E',"V:\Q Dup Check Needed\E")
    $comparisonFileSize=$comparisonFile.Length  
    $newPath=($_.FullName -replace 'Q:\\Backup Comparison\\E',"V:\Deleteable\Q Dup Check Needed\E")
    $createNewPath=Split-Path $newPath -Parent

    Write-Host $_.FullName # result is: Q:\Backup Comparison\E\Files\file[1].txt
    Write-Host $comparisonFile # result is null

    if ((Test-Path -LiteralPath $comparisonFile) && $_.Length -eq $comparisonFileSize) {
        $comparisonHash=(Get-FileHash -algorithm md5 $comparisonFile).Hash
        $sourceHash=((Get-FileHash -algorithm md5 $_).Hash)
        if ($sourceHash -eq $comparisonHash) {
            Write-Host $newPath
            mkdir $createNewPath
            mv  $comparisonFile $newPath
            Write-Host ""
        }
    }
}

问题与方括号有关。但是，它与New-Itemand有关mv。我通过添加以下内容调整了这些行LiteralPath：

$comparisonFile=Get-Item -LiteralPath ($_.FullName -replace 'Q:\\Backup Comparison\\E',"V:\Q Dup Check Needed\E")


Move-Item -LiteralPath $comparisonFile $newPath
