Powershell to get metadata of files - powershell

Question

I am looking to get metadata of a specified file (or directory of files). I am specifically looking for "Program Description" on .WTV files.
I found code, but it doesn't list that attribute. Some of that code looks like this:
foreach($sFolder in $folder)
{
$a = 0
$objShell = New-Object -ComObject Shell.Application
$objFolder = $objShell.namespace($sFolder)
foreach ($strFileName in $objFolder.items())
{ FunLine( "$($strFileName.name)")
for ($a ; $a -le 266; $a++)
{
if($objFolder.getDetailsOf($strFileName, $a))
{
$hash += #{ `
$($objFolder.getDetailsOf($objFolder.items, $a)) =`
$($objFolder.getDetailsOf($strFileName, $a))
} #end hash
$hash
$hash.clear()
I can see that attribute in File explorer.

Answer 1

The code you had #user1921849 has almost got it, but to address the original question more clearly you should use the Windows Shell Property System named properties, listed in the Windows devloper documentation for WTV files, and used in line 4 below.
$shell = new-object -com shell.application
$folder = $shell.namespace("\\MEDIA\Recorded Tv\")
$item = $folder.Items().Item('Person of Interest_WBBMDT_2013_11_26_21_01_00.wtv')
write-output $item.ExtendedProperty('System.RecordedTV.ProgramDescription')

Answer 2

Grab TagLib# from Nuget or various other places. Then check out this blog post showing how to use TagLib# to edit MP3 tags. Hopefully, it can retrieve the WTV tag you're looking for.

Answer 3

$shell = new-object -comobject shell.application
$ShFolder=$shell.namespace("\\MEDIA\Recorded Tv\")
$ShFile =$ShFolder.parsename("Person of Interest_WBBMDT_2013_11_26_21_01_00.wtv")
$count = 0
while ($count -le 294)
{
$ShRating = $ShFolder.getdetailsof($ShFile,$count)
$count
$ShRating
$count = $count+1
}
Program Description is item 272.

I have done a sample code which will check all file in a folder and export a csv file with all the metadata details. Please find the following powershell script.
Step 1. Create a file Fileproperty.ps1
Import-Module ".\Module\AddModule.psm1" -Force
$commands = {
$source = read-host "Enter folder path "
if ([string]::IsNullOrWhitespace($source)){
Write-host "Invalid file path, re-enter."
$source = $null
&$commands
}else{
$output = read-host "Enter output folder path "
if ([string]::IsNullOrWhitespace($output)){
Write-host "Invalid output path, re-enter."
$output = $null
&$commands
}else{
$outputfilename = read-host "Enter output file name "
if ([string]::IsNullOrWhitespace($outputfilename)){
Write-host "Invalid file name, re-enter."
$outputfilename = $null
&$commands
}else{
Get-FileMetaData -folder $source | Export-Csv -Path $output\$outputfilename.csv -Encoding ascii -NoTypeInformation
Write-host "Process has been done..."
}
}
}
}
&$commands
Step 2. Create a folder Module
Step 3. create another file Module/AddModule.psm1
$FunctionFiles = #(Get-ChildItem -Path $PSScriptRoot\*.ps1 -ErrorAction SilentlyContinue)
Foreach($fileItem in #($FunctionFiles))
{
Try
{
. $fileItem.fullname
}
Catch
{
Write-Error -Message "Vsts module -> Unable to import a function in file $($fileItem.fullname): $_"
}
}
Export-ModuleMember -Function $FunctionFiles.Basename
Step 4. create another file Module/Get-FileMetaData.ps1
Function Get-FileMetaData
{
Param([string[]]$folder)
$OutputList = New-Object 'System.Collections.generic.List[psobject]'
foreach($sFolder in $folder) {
$a = 0
$objShell = New-Object -ComObject Shell.Application
$objFolder = $objShell.namespace($sFolder)
foreach ($File in $objFolder.items())
{
$FileMetaData = New-Object PSOBJECT
for ($a ; $a -le 266; $a++)
{
if($objFolder.getDetailsOf($File, $a))
{
$hash += #{$($objFolder.getDetailsOf($objFolder.items, $a)) =
$($objFolder.getDetailsOf($File, $a)) }
$FileMetaData | Add-Member $hash
$hash.clear()
} #end if
} #end for
$a=0
$OutputList.Add($FileMetaData)
} #end foreach $file
} #end foreach $sfolder
return $OutputList
} #end Get-FileMetaData
Hope this will work for you.
