Progressbar directory recursive

I'm using this code to show a progressbar for copying files.

Code: Select all

		$selectedPath = "c:\test"		
		$files = Get-ChildItem $selectedPath -Filter *.txt
		
		if ($files -eq $null -or $files.Count -eq 0)
		{

			#No files to backup
			return
		}
		
		#Initialize the Progress Bar
		$progressbar1.Maximum = $files.Count
		$progressbar1.Step = 1
		$progressbar1.Value = 0
		
		#Create the Backup Folder
		$destination = ('{0}\\Backup' -f $selectedPath)
		[System.IO.Directory]::CreateDirectory($destination)
		
		#Copy the files and update the progress bar
		foreach ($file in $files)
		{
			Copy-Item ('{0}\\{1}' -f $selectedPath, $file) -Destination $destination
			$progressbar1.PerformStep()
		}
Now I would like to do the same thing with the recursive copy of directories

Code: Select all

        $files = Get-ChildItem -Path $selectedPath | Where-Object { $_.Name -match "@" }
	foreach ($file in $files)
	{
		Copy-Item ('{0}\\{1}' -f $selectedPath, $file) -Destination $destination -Recurse -Force
	$progressbar1.PerformStep()
	}
The directories have thousands of files but I see the progressbar only increase when the copy of the entire dir is completed while I would like the progression to be shown when copying all the files. How could I modify the script to get all this? Thank you

That is correct. A recursive copy blocks the thread until it is complete. Use the Job Tracker custom control set to create a job that displays a progress indicator.

I read what you indicated to me but I can not apply it to my case.
Could you tell me how to do it?
Thanks for your help.

The link I posted has complete instructions and an explanation that is better than I can do in a post. If this is your first time using PowerShell with forms you may need to take some time to read other articles on forms development.

If you just create a new form and add the control it serves as a demo of how the Job Tracker works.

I should also note that you file copy code does not make much sense. Why use recurse with a single file? Why do you need to rebuild the file name to copy it. Just copy the file.

It is much faster and more efficient to use RoboCopy to copy a large number of files.
