# How Operating Systems Display Cloud File Status Icons > A system for Windows or other operating systems to show synchronization status icons for files stored in various cloud services like OneDrive, Dropbox, or Google Drive. - **Patent:** US 10402375 - **Original title:** Cloud content states framework - **Owner:** Microsoft Technology Licensing LLC - **Granted:** 2019 - **Status:** Active - **Times cited:** 4 - **Field:** consumer_electronics, software ## What it does This patent describes a software framework that acts as a middleman between your computer's file explorer and various cloud storage services. It manages two types of status icons: primary states (like 'synced,' 'downloading,' or 'error') and custom states defined by specific cloud providers (like 'shared' or 'locked'). The framework identifies available display slots next to a file name in your file explorer, prioritizes the primary synchronization icons, and then fills the remaining slots with the custom icons. This ensures that no matter which cloud service you use, the file explorer displays a consistent set of status indicators. ## What it does NOT cover - Does not cover the actual file synchronization process itself (the uploading or downloading of bits). - Does not cover cloud storage services that do not integrate with the operating system's file explorer. - Does not cover the underlying network protocols used to communicate with cloud servers. - Does not cover non-visual methods of indicating file status, such as audio alerts or haptic feedback. ## The clever bit The framework treats status icons as a resource-constrained UI problem by identifying 'available slots' and prioritizing system-level synchronization status over third-party custom status, preventing icon clutter. ## Real-world examples 1. OneDrive status icons in Windows File Explorer 2. Dropbox sync status icons in Windows File Explorer 3. Google Drive for Desktop file status indicators ## Why it matters Before this framework, different cloud storage apps had to 'hack' the file explorer to show their own icons, often causing conflicts or performance issues. By standardizing how these icons are rendered, Microsoft enabled a cleaner, more reliable experience for users who juggle multiple cloud services simultaneously on the same machine. ## Frequently asked questions ### What does How Operating Systems Display Cloud File Status Icons cover?
