Powershell - rename file using Date Taken attribute

Question

I have a stack load of images and videos on my Samsung phone. I copied these images to a USB then onto my PC.

I want to use Powershell to rename these files based on their Date Taken attribute.

Format required = yyyy-MM-dd HH.mm.ss ddd

I have been using a Powershell script (see below) that does this beautifully using the Date Modified attribute, but the copy above somehow changed the Date Modified value on me (WTH!), so I can't use that now (as its not accurate).

Get-ChildItem | Rename-Item -NewName {$_.LastWriteTime.ToString("yyyy-MM-dd HH.mm.ss ddd") + ($_.Extension)}

In summary - is there a way to change the file name based on the Date Taken file attribute? Suggestions I have seen online require use of the .NET System.Drawing.dll and convoluted code (I'm sure it works, but damn its ugly).

Answer 1

I 'glued' together a bunch of other answers to make a bulk script. Credit to those, but Chrome crashed and I lost those other webpages on Stack. This works on photo files only and will rename all files to YYYYMMDD_HHMMSS.jpg format.

Here it is:

$nocomment = [reflection.assembly]::LoadWithPartialName("System.Drawing")
get-childitem *.jpg | foreach {
    $pic = New-Object System.Drawing.Bitmap($_.Name)
    $bitearr = $pic.GetPropertyItem(36867).Value
    $string = [System.Text.Encoding]::ASCII.GetString($bitearr)
    $date = [datetime]::ParseExact($string,"yyyy:MM:dd HH:mm:ss`0",$Null)
    [string] $newfilename = get-date $date -format yyyyMd_HHmmss
    $newfilename += ".jpg"
    $pic.Dispose()
    rename-item $_ $newfilename -Force
    $newfilename
}
