Disk Space Cleanup and Report Script

Monitoring & HealthJanuary 14, 2025

This PowerShell script helps maintain system performance by identifying large files and folders on specified drives. It not only lists these files but also offers an option to delete them, making it an effective tool for disk space management.

powershell
# Define the path to search for large files
$searchPath = "C:\"
# Set the minimum file size threshold in MB
$sizeThresholdMB = 100
$sizeThresholdBytes = $sizeThresholdMB * 1MB

# Get files larger than the threshold in the specified path
$largeFiles = Get-ChildItem -Path $searchPath -Recurse -File | Where-Object { $_.Length -gt $sizeThresholdBytes }

# Display file details: Name, Size (MB), and Path
$largeFiles | Select-Object Name, @{Name="Size (MB)"; Expression={[math]::round($_.Length / 1MB, 2)}}, FullName | Format-Table -AutoSize

# Ask user for deletion
$deleteFiles = Read-Host "Do you want to delete any of these files? (Y/N)"
if ($deleteFiles -eq 'Y') {
    foreach ($file in $largeFiles) {
        # Prompt for each file deletion
        $confirmDelete = Read-Host "Do you want to delete $($file.FullName)? (Y/N)"
        if ($confirmDelete -eq 'Y') {
            Remove-Item -Path $file.FullName -Force
            Write-Host "Deleted: $($file.FullName)"
        }
    }
} else {
    Write-Host "No files will be deleted."
}

Write-Host "Disk space cleanup operation completed."
