Get datetaken attribute on file - powershell

Question

I am trying to write a script that will get the DATETAKEN attribute from a photo and create a folder structure based on that and move the file to this new location. I have found scripts on google that I'm trying to use but when I running it, it returns:
PS C:\Temp> C:\Temp\MovePhoto.ps1
GAC Version Location
--- ------- -------- True v4.0.30319
C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Drawing\v4.0_4.0.0....
Move-Item : The process cannot access the file because it is being
used by another process. At C:\Temp\MovePhoto.ps1:43 char:5
+ Move-Item $FileFullName "$FileDirFull\$FileBaseNameNU"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : WriteError: (C:\NoBackup\TES...RA\IMG_1372.JPG:FileInfo) [Move- Item],
IOException
+ FullyQualifiedErrorId : MoveFileInfoItemIOError,Microsoft.PowerShell.Commands.MoveItemCommand
If I do the script without the SystemDrawing line it works. But then I can't get the DATETAKEN attribute. I just can't figure out what I am missing.
Here is the script
[reflection.assembly]::LoadWithPartialName("System.Drawing")
$FileAll = (Get-ChildItem $SourcePath -Recurse | where {!$_.psiscontainer} | Select-Object Name,Fullname,BaseName,Extension,CreationTime,LastWriteTime,Length,#{Name="MD5";Expression={Get-Md5Hash $_.fullname}} | group MD5 | Where {$_.Count -gt 1 } | %{$_.Group} | sort MD5)
foreach ($File in $FileAll) {
$FileBaseName = $File.BaseName
$FileExtension = $File.Extension
$FileFullName = $File.FullName
$FileBaseNameNu = $FileBaseName + $FileExtension
$FileName = $File.Name
}
$foo = New-Object -TypeName System.Drawing.Bitmap -ArgumentList $FileFullName
$date = $foo.GetPropertyItem(36867).Value[0..9]
$arYear = [Char]$date[0],[Char]$date[1],[Char]$date[2],[Char]$date[3]
$arMonth = [Char]$date[5],[Char]$date[6]
$arDay = [Char]$date[8],[Char]$date[9]
$strYear = [String]::Join("",$arYear)
$strMonth = [String]::Join("",$arMonth)
$strDay = [String]::Join("",$arDay)
$DateTaken = $strYear + "-" + $strMonth + "-" + $strDay
$FileLastWriteTime = $File.LastWriteTime
$FileDirYear = $FileLastWriteTime.Year
$FileDirDate = $FileLastWriteTime.ToShortDateString()
$FileDirFull = "$DestinationPath\DUBLETTER\$FileDirYear\$DateTaken"
# Create destination path
if ((Test-Path $FileDirFull) -eq $false) {
New-Item -Path $FileDirFull -ItemType Directory
}
if (Test-Path (Join-Path $FileDirFull $File.Name)) {
$n = 0
while ((Test-Path (Join-Path $FileDirFull $FileBaseNameNU)) -eq $true){
$FileBaseNameNU = $FileBaseName + "-" + ++$n + $FileExtension
}
}
Move-Item $FileFullName "$FileDirFull\$FileBaseNameNU"
}

Answer 1

Can you try to replace
[reflection.assembly]::LoadWithPartialName("System.Drawing")
by
Add-Type -AssemblyName "system.drawing"
Forget it, your trouble is with your file C:\NoBackup\TES...RA\IMG_1372.JPG wich can't be moved because it's open (seems to be open for usage in $foo var). Try first to copy it. You perhaps can use $foo.Dispose() before Move-Item $FileFullName "$FileDirFull\$FileBaseNameNU"

I've done this in VBScript, using GetDetailsOf()... see MSDN
This can be done using PowerShell, see... Scripting Guys
There may be a .NET method way of doing this, i.e.: more "native" to PS.
