如何使用PowerShell的Compress-Archive实现多线程批量压缩多个文件夹

核心逻辑说明 #

完全保留原有脚本逻辑：自动排除Enter开头的目录、检测目录下是否已有zip包避免重复压缩，新增并发控制参数，可根据设备性能自行调整同时执行的压缩任务数量。 #

版本1：PowerShell 7+ 适用（语法简洁性能最优） #

# 打开文件夹选择对话框
function Select-Folder {
    Add-Type -AssemblyName System.Windows.Forms
    $folderDialog = New-Object System.Windows.Forms.FolderBrowserDialog
    $folderDialog.Description = "请选择待处理的根目录"
    $result = $folderDialog.ShowDialog()
    if ($result -eq [System.Windows.Forms.DialogResult]::OK) {
        return $folderDialog.SelectedPath
    }
    return $null
}

function Zip-Folders {
    param(
        [String]$FolderPath,
        [int]$MaxParallel = 8 # 可自行调整最大并行任务数，建议和CPU物理核心数保持一致
    )
    if ([string]::IsNullOrEmpty($FolderPath)) {
        $FolderPath = Select-Folder
        if ($null -eq $FolderPath) { return }
    }

    # 获取所有待处理目录
    $targetFolders = Get-ChildItem -Path $FolderPath -Directory -Exclude Enter*

    # 并行处理压缩任务
    $targetFolders | ForEach-Object -Parallel {
        $folder = $_
        $zipName = "$($folder.Name) Photos.zip"
        $zipFullPath = Join-Path -Path $folder.FullName -ChildPath $zipName

        # 检查是否已有压缩包，和原逻辑保持一致，存在任意zip则跳过
        if (-not (Get-ChildItem -Path $folder.FullName -Filter *.zip -File | Select-Object -First 1)) {
            Write-Host "正在压缩：$($folder.FullName)"
            Compress-Archive -Path (Join-Path $folder.FullName -ChildPath *) -DestinationPath $zipFullPath -Force
            Write-Host "压缩完成：$zipFullPath"
        } else {
            Write-Host "已跳过：$($folder.Name) 已有压缩包"
        }
    } -ThrottleLimit $MaxParallel
}

# 直接调用Zip-Folders即可弹出文件夹选择框
# Zip-Folders

版本2：兼容PowerShell 5.1（Windows系统自带版本适用） #

如果不想升级PowerShell，可使用基于RunspacePool的兼容版本，性能远高于单线程执行：

# 打开文件夹选择对话框
function Select-Folder {
    Add-Type -AssemblyName System.Windows.Forms
    $folderDialog = New-Object System.Windows.Forms.FolderBrowserDialog
    $folderDialog.Description = "请选择待处理的根目录"
    $result = $folderDialog.ShowDialog()
    if ($result -eq [System.Windows.Forms.DialogResult]::OK) {
        return $folderDialog.SelectedPath
    }
    return $null
}

function Zip-Folders {
    param(
        [String]$FolderPath,
        [int]$MaxParallel = 8 # 可自行调整最大并行任务数
    )
    if ([string]::IsNullOrEmpty($FolderPath)) {
        $FolderPath = Select-Folder
        if ($null -eq $FolderPath) { return }
    }

    # 获取所有待处理目录
    $targetFolders = Get-ChildItem -Path $FolderPath -Directory -Exclude Enter*
    if ($targetFolders.Count -eq 0) {
        Write-Host "未找到待处理的目录"
        return
    }

    # 初始化RunspacePool
    $runspacePool = [RunspaceFactory]::CreateRunspacePool(1, $MaxParallel)
    $runspacePool.Open()
    $jobs = @()

    foreach ($folder in $targetFolders) {
        $powerShell = [PowerShell]::Create()
        $powerShell.RunspacePool = $runspacePool
        $powerShell.AddScript({
            param($folder)
            $zipName = "$($folder.Name) Photos.zip"
            $zipFullPath = Join-Path -Path $folder.FullName -ChildPath $zipName
            # 检查是否已有压缩包
            if (-not (Get-ChildItem -Path $folder.FullName -Filter *.zip -File | Select-Object -First 1)) {
                Compress-Archive -Path (Join-Path $folder.FullName -ChildPath *) -DestinationPath $zipFullPath -Force
                return "压缩完成：$zipFullPath"
            } else {
                return "已跳过：$($folder.Name) 已有压缩包"
            }
        }).AddArgument($folder)
        $jobs += @{
            PS = $powerShell
            AsyncResult = $powerShell.BeginInvoke()
        }
    }

    # 接收执行结果
    foreach ($job in $jobs) {
        $result = $job.PS.EndInvoke($job.AsyncResult)
        Write-Host $result
        $job.PS.Dispose()
    }

    # 释放资源
    $runspacePool.Close()
    $runspacePool.Dispose()
}

# 直接调用Zip-Folders即可弹出文件夹选择框
# Zip-Folders
