I am trying to list some of my mp3 files with Powershell.

I have tried 

ls C:\test | Format-List -Property Name,Length

which gives me 

Name   : testfile.mp3
Length : 10058533

The length is the size of the file which I don't care for at this moment.

Knowing that I can choose duration in File Explorer for a column heading I thought to re-write the above as 

ls C:\test | Format-List -Property Name,Duration

but what I get is 

Name   : testfile.mp3

How can I tell Powershell to return the minutes and seconds for the duration? Or even just the seconds. Thanks in advance

To get the length of an mp3, probably the easiest way is to make use of what explorer uses, a Shell objekt.

I'm afraid I don't have a one-liner for you, but you can always make a script that you call.

$path = 'M:\Musikk\awesome_song.mp3'
$shell = New-Object -COMObject Shell.Application
$folder = Split-Path $path
$file = Split-Path $path -Leaf
$shellfolder = $shell.Namespace($folder)
$shellfile = $shellfolder.ParseName($file)

write-host $shellfolder.GetDetailsOf($shellfile, 27);

More information can be found here: http://powershell.com/cs/blogs/tobias/archive/2011/01/07/organizing-videos-and-music.aspx

Edit: The reason this method is necessary is because the length information resides with the other metadata of the file.

  • I wasn't asking for one-liner so no deduction there :) And yes this does give me what I am asking for now I need to loop it for multiples files :) Thanks – Darius Jan 20 '14 at 23:57
