Process bar Powershell

Question

I need to copy an HDD to my NAS but I want only the images and videos while conserving the folder and subfolder structure.

I have this code that works but would like to add a progress bar.

PS : I am new to powershell so I would love to have some recommendations or a way to improve my code to be more solid, so it doesn't break or something in the middle of copying (I have around 90GB of videos and photos to copy).

Thank you in advance!

My code :

$sourcePath = 'D:\Users\Dave'
$destPath = 'Z:\Dave Dimov\Photos\HDD 1'
    
Get-ChildItem $sourcePath -Recurse -Include '*.png', '*.jpg', '*.jpeg' , '*.mov' , '*.mp4' | Foreach-Object ` {
    
    $destDir = Split-Path ($_.FullName -Replace [regex]::Escape($sourcePath), $destPath)

    if (!(Test-Path $destDir))
    
{
New-Item -ItemType directory $destDir
}

Copy-Item  $_ -Destination $destDir

}

use `robocopy` ... it is designed for what you describe. [*grin*] — Lee_Dailey, Feb 16 '21 at 23:04
Thank you, will check it out and see what I can do. Will update the code if it works or I get suck again, lol — Auth3ntical, Feb 16 '21 at 23:12

Based off Trevor Sullivans "Copy-WithProgress" answer, this could work for you.

$sourcePath = 'D:\Users\Dave'
$destPath = Test-Path -Path 'Z:\Dave Dimov\Photos\HDD 1'
    if(!$destPath){New-Item -ItemType directory $destDir}
    
$DIRe = Get-ChildItem $sourcePath -Filter '*.png', '*.jpg', '*.jpeg' , '*.mov' , '*.mp4' -Recurse 
Copy-WithProgress $DIRe -Destination $destPath -Verbose

This is what works for me now :
