Question

我是PowerShell的新手，我没有通过搜索来找到任何相关信息。所以我会在这里询问是否有人知道这是否可行以及如何做到这一点......

我在一个文件夹中有1000个mp3文件。我想将它们分成子文件夹，但每个子文件夹应该有1小时的播放时间，或者至少尽可能接近1小时（最好超过1小时，而不是更少）。

所以我必须查看mp3文件的长度（通常是2-4分钟）。我想首先获得足够的mp3文件，这样总共可以播放1小时的游戏时间。然后将它们移动到子文件夹，并将其命名为List *n*，其中 n 为每个子文件夹递增。喜欢：列表1，列表2，列表3

这可能吗？

更新：这是工作脚本！管理解决它！ :) 编辑播放列表路径（主目录，将创建所有子文件夹）。还要编辑播放列表长度！

Function Get-MP3Data
{
    [CmdletBinding()]
    [Alias()]
    [OutputType([Psobject])]
    Param
    (
        [String] [Parameter(Mandatory=$true, ValueFromPipeline=$true)] $Directory
    )

    Begin
    {
        $shell = New-Object -ComObject "Shell.Application"
    }
    Process
    {

        Foreach($Dir in $Directory)
        {
            $ObjDir = $shell.NameSpace($Dir)
            $Files = gci $Dir| ?{$_.Extension -in '.mp3','.mp4'}

            Foreach($File in $Files)
            {
                $ObjFile = $ObjDir.parsename($File.Name)
                $MetaData = @{}
                $MP3 = ($ObjDir.Items()|?{$_.path -like "*.mp3" -or $_.path -like "*.mp4"})
                $PropertArray = 0,1,2,12,13,14,15,16,17,18,19,20,21,22,27,28,36,220,223

                Foreach($item in $PropertArray)
                { 
                    If($ObjDir.GetDetailsOf($ObjFile, $item)) #To avoid empty values
                    {
                        $MetaData[$($ObjDir.GetDetailsOf($MP3,$item))] = $ObjDir.GetDetailsOf($ObjFile, $item)
                    }

                }

                New-Object psobject -Property $MetaData |select *, @{n="Directory";e={$Dir}}, @{n="Fullname";e={Join-Path $Dir $File.Name -Resolve}}, @{n="Extension";e={$File.Extension}}
            }
        }
    }
    End
    {
    }
}

# Create playlist
$TotalLength = 0
$MaxLength = 3600
$TempPlaylist = @()
$PlaylistName = 1
$PlaylistPath = "C:\Users\Admin\Desktop\New folder"

if ($TotalLength -lt $MaxLength)
{   
    ForEach($item in ($PlaylistPath |Get-Mp3Data)){

        # Get all song names and song durations
        $SongName = $item.Fullname
        $Seconds = [int](([datetime]$item.Length).TimeOfDay.TotalSeconds)

        # Append song duration to total length and add song to temporary playlist
        $TotalLength += $Seconds
        $TempPlaylist += ,$SongName

        # Create a folder for the playlist if it doesn't exist
        if (!(test-path $PlaylistPath\$PlaylistName))
        {
            New-item -ItemType Directory -Force -Name $PlaylistName -Path $PlaylistPath
            Write-Host Created new folder $PlaylistName
        }

        # Check if the total length is >= maxlength, then move temporary playlist to a new folder
        if ($TotalLength -ge $MaxLength)
        {   
            # Loop through all songs in the temporary playlist
            For($i=0; $i -lt $TempPlaylist.length; $i++)
            {
                Move-Item -Path $TempPlaylist[$i] -Destination $PlaylistName
                Write-Host Moved file $TempPlaylist[$i] to $PlaylistName
            }

            # Increment playlist folder name
            $PlaylistName++

            # Reset the temporary playlist
            $TempPlaylist = @()

            # Reset the temporary playlist length
            $TotalLength = 0
        }
    }
}

要向其添加随机化（以便mp3文件在插入播放列表之前随机排序），只需更改

ForEach($item in ($PlaylistPath | Get-Mp3Data)){

到

ForEach($item in ($PlaylistPath | Get-Mp3Data) | Sort-Object {Get-Random}){

按歌曲持续时间将文件拆分到子文件夹
