按歌曲持续时间将文件拆分到子文件夹中

Question

我对PowerShell完全陌生，通过搜索它，我没有发现任何关于它的东西。所以我会在这里询问是否有人知道这是否可能，以及如何做到.

我在一个文件夹中有1000个mp3文件。我想把它们分成子文件夹，但是每个子文件夹的播放时间应该是1小时，或者至少尽可能接近1小时(最好大于1h，而不是更短)。

因此，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，这样总共就有1小时的播放时间了。然后将它们移到子文件夹中，并将其命名为List *n*，其中n对每个子文件夹递增。类似:列表1，列表2，列表3

这个是可能的吗？

Answer 1

更新:这是工作脚本！编辑播放列表路径(主目录，将创建所有子文件夹)。同时编辑播放列表的长度！

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
        }
    }
}

若要向其添加随机化(以便在插入播放列表之前对mp3文件进行随机排序)，只需更改即可。

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

至

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