На самом деле разницы нет, просто другое не знаю. »

Vovusja, тогда куда проще будет использовать PowerShell. Что-то наподобие такого (без каких-либо проверок и т.п.):

Код:

$sSourceFolder   = 'C:\Мои проекты\0036\Sample'
$sSourceFileMask = 'Sample.exe'
$sPatchFile      = 'C:\Мои проекты\0036\Patch.bin'

$iPosition     = 0x100
$aByteTemplate = [System.Byte[]](0x0B, 0x02, 0x09, 0x00)

$aBuffer       = New-Object -TypeName System.Byte[] -ArgumentList $aByteTemplate.Length


Get-ChildItem -Path $sSourceFolder -Recurse -File -Include $sSourceFileMask -Force |`
    ForEach-Object -Begin {
        $aPatchContent = [System.Byte[]](Get-Content -Encoding Byte -Path $sPatchFile)
    } -Process {
        Write-Host $_.FullName -ForegroundColor Yellow -NoNewline

        $oFileStream = $_.Open([System.IO.FileMode]::Open, [System.IO.FileAccess]::ReadWrite)

        try {
            $oFileStream.Seek($iPosition, [System.IO.SeekOrigin]::Begin) | Out-Null
            $oFileStream.Read($aBuffer, 0, $aByteTemplate.Length) | Out-Null

            if (([System.Collections.IStructuralEquatable]$aByteTemplate).Equals($aBuffer, [System.Collections.StructuralComparisons]::StructuralEqualityComparer)) {
                $oFileStream.Seek($iPosition, [System.IO.SeekOrigin]::Begin) | Out-Null
                $oFileStream.Write($aPatchContent, 0, $aPatchContent.Length) | Out-Null
                Write-Host "`tOk" -ForegroundColor Green
            } else {
                Write-Host "`tCan't find bytes template in file content" -ForegroundColor Red
            }
        } finally {
            $oFileStream.Close()
        }
    }
