Adding a Write Progress bar to a script Powershell - powershell

Question

I'm actually writing a powershell script that sort pictures and videos by dates. The script works fine but i would like to add a progress bar, and i don't know where to start, this might be a bit tricky for me, that's why i'm looking for help.
Here is the function that sort pictures
foreach ($file in $Images)
{
$Directory = $destinationDirectory + "Pictures\" + $file.LastWriteTime.Date.ToString('yyyy') + "\" + $file.LastWriteTime.Date.ToString('MMM')
if (!(Test-Path $Directory))
{
New-Item $directory -type directory
}
Copy-Item $file.fullname $Directory
}
I read the documentation about the Write-progress function but i really don't know how i'm supposed to manage it in this script

Answer 1

Use a variable to hold the count of files copied, increment it for each operation, then display the percentage. The example for Write-Progress has a pretty good example.
I'd recommend using the PowerShell pipeline as well instead of a foreach.
Something like this (remove the -WhatIfs when you're ready):
$images |
ForEach-Object
-Begin {
$filesCopied = 0
} `
-Process {
$Directory = "$destinationDirectory\Pictures\$($_.LastWriteTime.Date.ToString('yyyy'))\$($_.LastWriteTime.Date.ToString('MMM'))"
if (!(Test-Path $Directory)) {
New-Item $directory -type directory -WhatIf
}
Copy-Item $_.fullname $Directory -WhatIf
$filesCopied += 1
Write-Progress -Activity "Copied $_.FullName" `
-CurrentOperation "Copying $_" `
-Status "Progress:" `
-PercentComplete (($filesCopied / $Images.Count) * 100)
}

The Write-Progress cmdlet needs a bit of math to make it work for your situation. This should do it:
$i = 1
foreach ($file in $Images)
{
$Directory = $destinationDirectory + "Pictures\" + $file.LastWriteTime.Date.ToString('yyyy') + "\" + $file.LastWriteTime.Date.ToString('MMM')
if (!(Test-Path $Directory))
{
New-Item $directory -type directory
}
Copy-Item $file.fullname $Directory
[int]$Percent = $i / $Images.count * 100
Write-Progress -Activity "Copying photos" -Status "$Percent% Complete:" -PercentComplete $Percent
$i++
}
First, start with a counter variable $i and set it to 1 to represent the first item. This is setup outside the loop so that it doesn't reset back to 1 every time the loop runs.
Then, inside the loop the $Percent variable is defined by dividing the value of $i by the number of items and multiplying it by 100. Then, Write-Progress is called with the necessary parameters to display the progress. Then the counter is incremented upward by one using $i++.
Side note: $Percent is set to be an integer by placing [int] in front of it, which forces it to display whole numbers. If you want to see fractional values, just remove the [int].
