try $hasZoneId = Get-Item $file.FullName -Stream Zone.Identifier -ErrorAction SilentlyContinue
In environments running very old versions of PowerShell or where Unblock-File is not available, the streams.exe tool (part of the Sysinternals Suite) or manual stream removal is required. The manual PowerShell method is:
# Summary Write-Host "`n" + ("=" * 60) -ForegroundColor Cyan Write-Host "RECURSIVE UNBLOCK COMPLETE" -ForegroundColor Cyan Write-Host "=" * 60 -ForegroundColor Cyan Write-Host "Total files scanned: $total" -ForegroundColor White Write-Host "Files unblocked: $unblocked" -ForegroundColor Green Write-Host "Log saved to: $LogPath" -ForegroundColor Yellow recursively unblock files powershell
Run this command from your PowerShell terminal (replace the path with your target folder): powershell
If the command encounters files it can't access (like system files), it might throw errors. To ignore these and keep going: powershell try $hasZoneId = Get-Item $file
Write-Progress -Activity "Unblocking Files" -Completed
To prevent errors and speed up execution, it is best practice to filter for files only, as directories themselves do not typically hold a Zone.Identifier in the same manner, and unblocking a directory object is unnecessary. : Indicates a file was downloaded from the Internet zone
