Could anyone please assist me on this issue? I have been trying to resolve this issue from last one week but I am not able to resolve this and need your help.

What is the goal of this script?

1. Need to delete big SQL dump files remotely.
2. When script is launched, we need to click on ok while parent folder is selected/highlighted.
3. After then we need click on ok so that we can go to its subfolder.
4. Finally we need to select the files and hit OK. It will delete the selected files.
5. For this, a GUI PS script needs to be created.
6. Files to be deleted are under subfolder of another subfolder.

Error while executing this script:

**`Get-ChildItem : Cannot find path ‘C:UsersUjjwal Mandal@{name=All Documents; Size=6.18 GB}’ because it does not exist.
At D:projecttest.ps1:30 char:20

• $child1= $output | Get-ChildItem | Out-GridView -Title “Select server …`
  **

My PowerShell code for this

Add-Type -AssemblyName PresentationFramework
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
$TempFile = [io.path]::GetTempFileName()
$form = New-Object System.Windows.Forms.Form
$form.Text = "Fix low space issue"
$form.size =  New-Object System.Drawing.Size(900,400)
$remdmp = New-Object System.Windows.Forms.Button
$remdmp.Location = New-Object System.Drawing.Size(300,35)
$remdmp.Size = New-Object System.Drawing.Size(300,45)
$remdmp.Text = "Remove dump Files"
$remdmp.Font = [System.Drawing.Font]::new('Microsoft Sans Serif', 10, [System.Drawing.FontStyle]::Bold)
$remdmp.Add_Click({
Remove-Item $TempFile -ErrorAction SilentlyContinue
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')
$svrs ="TM-ND0276"
$path = "\TM-ND0276d$"
$size = 0
$decimalPlaces = 2
$output = @()
$data=Get-ChildItem -Directory $path | ForEach-Object {
 $size += (Get-ChildItem -Recurse $_.FullName | Measure-Object -Property Length -Sum).Sum
 $output += New-Object PSObject -Property @{
 name = $_.Name
 Size = "{0:N$decimalPlaces} GB" -f ((Get-ChildItem -Recurse $_.FullName | Measure-Object -Property Length -Sum).Sum / 1GB)
 }
}

$output | Sort-Object -Descending -Property Size | Out-GridView -Title "select" -PassThru 
$child1= $output | Get-ChildItem | Out-GridView -Title "Select server name folder you want to delete the dump files from" -PassThru
$child2= $child1 | Get-ChildItem | Out-GridView -Title "Select files you want to delete" -PassThru
if($child2) {
$child2 | Remove-Item -Recurse -Force
$msgbox=[System.Windows.MessageBox]::Show('Dump files have been deleted. Check notepad for available free space in D drive')
$dskspce=Invoke-Command -ComputerName $svrs -ScriptBlock {Get-WmiObject -Class win32_logicaldisk | Format-Table DeviceId, MediaType, @{n="Size";e={[math]::Round($_.Size/1GB,2)}},@{n="FreeSpace";e={[math]::Round($_.FreeSpace/1GB,2)}} }

$dskspce | Format-Table > $TempFile | Notepad $TempFile
}
else{
$msgbox=[System.Windows.MessageBox]::Show('Action has been cancelled. Script will stop here!')
}
})
$Form.Controls.Add($remdmp)

$QUIT = New-Object 'System.Windows.Forms.Button'
$QUIT.DialogResult = 'OK'
$QUIT.Location = '300, 200'
$QUIT.Margin = '5, 5, 5, 5'
$QUIT.Name = 'buttonOK'
$QUIT.Size = '300, 50'
$QUIT.BackColor ="LightGray"
$QUIT.ForeColor ="black"
$QUIT.Text = '&CLOSE'
$QUIT.Font = [System.Drawing.Font]::new('Microsoft Sans Serif', 10, [System.Drawing.FontStyle]::Bold)
$QUIT.UseCompatibleTextRendering = $True
$QUIT.UseVisualStyleBackColor = $False
$QUIT.Add_Click({$form.Add_FormClosing({$_.Cancel=$false});$form.Close()})    
$QUIT.Show()#$QUIT.Hide()
$form.Controls.Add($QUIT)
$form.showdialog()

It looks like object TypeName of output should be “System.IO.DirectoryInfo” however, it is “System.Management.Automation.PSCustomObject” that’s why I am getting this error?

Could anyone please take a look and assist me here? Kindly let me know if you any question.

I have tried all the articles I found on the internet also gone through a PowerShell book but didn’t find much information regarding this error and resolution.

When I click on OK button(after selecting any subfolder folder) it should take me to another subfolder but unfortunately it is not.
