Contributed a focused documentation enhancement to the MicrosoftDocs/windows-driver-docs-ddi repository, clarifying the Asynchronous Procedure Call (APC) requirements for Windows file query APIs. The update consolidated guidance for FltQueryDirectoryFile, FltQueryDirectoryFileEx, and FltQueryInformationFile, specifying prerequisites and usage conditions to reduce misconfiguration risks. Leveraging Markdown and documentation best practices, the work improved developer onboarding by making API requirements explicit and traceable to a dedicated commit. This effort aligned with internal standards and enhanced the maintainability of Windows driver documentation, ensuring that developers have clear, actionable information when working with file query APIs in kernel-mode environments. No bugs were addressed.
