## Description

QuickLook is a utility for the Windows operating system that provides instant file previews through keyboard shortcuts. It allows users to inspect the contents of documents, media, and code without the need to launch the associated software applications.

The application integrates directly into the system file manager and open dialog windows, ensuring a consistent preview experience across the operating system. It utilizes a modular plugin architecture that enables the rendering of diverse file formats, including office documents, engineering drawings, and vector graphics, without requiring the installation of the original creation software.

The software maintains system stability by rendering previews in isolated processes and supports regional customization through decoupled resource files. Users can manage their preferences and settings through persistent storage, ensuring that configurations remain accessible across different sessions.
