# Symptoms

Multiple folders exist in C:\Users\HCIOrchestrator\AppData\Local\Temp containing AzStackHci.EnvironmentChecker nuget contents.

Issue Validation

To confirm the scenario that you are encountering is the issue documented in this article, please run this script:

$nugetName = 'AzStackHci.EnvironmentChecker'
$tempPath = 'C:\Users\HCIOrchestrator\AppData\Local\Temp'
$tempNugetFolders = Get-ChildItem -Path $tempPath -Recurse -Filter "$nugetName.*" -Directory -ErrorAction SilentlyContinue
$tempNugetFolders.Count

If it returns a number of folders the nuget may be taking up space, follow the mitigation steps below to resolve the issue on the node.

Mitigation Details

On each node where the issue exists, run the following script:

$nugetName = 'AzStackHci.EnvironmentChecker'
$tempPath = 'C:\Users\HCIOrchestrator\AppData\Local\Temp'
$tempNugetFolders = Get-ChildItem -Path $tempPath -Recurse -Filter "$nugetName.*" -Directory -ErrorAction SilentlyContinue
foreach ($tnf in $tempNugetFolders)
{
    try
    {
        $randomFileNameRegex = '^[a-z0-9]{8}\.[a-z0-9]{3}$'
        $tnfParent = Split-Path -Path $tnf.FullName -Parent
        $parentFolderName = Split-Path -Path $tnfParent -Leaf
        if (-not ($parentFolderName -match $randomFileNameRegex))
        {
            Write-Host "Skipping removal of temp nuget folder $tnfParent as it does not match expected pattern."
            continue
        }
        $allowedAgeDays = 1
        $age = (Get-Date) - (Get-Item -Path $tnfParent | ForEach-Object LastWriteTime)
        if ($age.TotalDays -lt $allowedAgeDays)
        {
            Write-Host "Skipping removal of temp nuget folder $tnfParent as its last write time was $($age.TotalDays) days ago, which is less than $allowedAgeDays days."
            continue
        }
        Write-Host "Removing temp nuget folder $tnfParent"
        Remove-Item -Path $tnfParent -Recurse -Force -ErrorAction Stop
    }
    catch
    {
        Write-Host "Unable to remove temp nuget folder. Exception: $($_.Exception.GetType().FullName): $($_.Exception.Message)" -ForegroundColor Red
    }
}
