+# Test block-clone functionality on a temporary ReFS VHD.
+#
+# Requires:
+#   - Administrator privileges
+#   - Windows Server, or Windows 10/11 Pro for Workstations (ReFS support)
+#   - Hyper-V PowerShell module (for New-VHD), or diskpart fallback
+#
+# Usage:
+#   # From an elevated PowerShell prompt:
+#   .\scripts\test_scripts\block-clone-test-windows.ps1 [-TestBinary <path>]
+#
+# If -TestBinary is not given, defaults to build\windows\x64\debug\zencore-test.exe
+# relative to the repository root.
