I'm using this module, called MPTag, in Powershell: http://powershell.com/cs/media/p/9129.aspx

It's used for editing an audio track's metadata. It works great, but I need to add leading 0's to track numbers and it's not accepting the leading zero. It just saves the integer without the leading zero.

What I'm currently using is: 

$songmeta = get-mediainfo $song
$song.track = 01
$song.save()

I've also tried adding .tostring, but it still comes out without the zero. Anyone have any ideas how I can do this? I'm very new to scripting, so I can't really understand the taglib source archive that's linked to on the download page. Is there any way I can get these leading zeros in? If not, does anyone know any other metadata editing method that would work? Thanks for any help.

EDIT: work-around solution I've found is to use FFMPEG's metadata editor. It allows you to write the leading zero. More info on this wiki page.

    That library may not support what you're trying to do. If I had to guess, it uses number internally for that field, with a default `toString()` for writing. You may be able to modify [the source code](http://taglib-sharp.sourcearchive.com/) to do what you want. – Ryan Bemrose May 24 '16 at 19:46

    The one thing I'd try is use quotes to force the data type to string and see if that helps. `$song.track = "01"` – Ryan Bemrose May 24 '16 at 19:47
  • I tried quotes, no good, unfortunately. But thanks for the advice. How exactly would I begin to edit the source code? Do I have this library downloaded on my computer? Or would I just edit the .dll of the module itself? Edit: Nevermind just noticed the .dll came with the library. I'll examine it and see if there's anything obvious I can change. – Matthew Goode May 24 '16 at 20:38
  • I've created a new question as I think I've entered a whole new world of discussion. If you know anything about editing source code, feel free to help me out! Thanks for your help though @RyanBemrose – Matthew Goode May 24 '16 at 21:42

What I am currently using is the Split function. It may not be exactly what you are looking for, but it should be a 90% solution. I have to rip all of my cds after I lost my RAID.

Example file: 01 - Song.mp3
$files = get-childitem "your_directory" -filter *.mp3
foreach($a in $files)
{
    $b = $a.basename.Split(' - ')
    $c = '0'+$b[0]+' - '+$b[1]+$a.extension
    Rename-Item $a.Fullname -NewName $c
}
