The `FileSyncShell64.dll` file is a component developed by Microsoft Corporation and is specifically associated with Microsoft OneDrive. OneDrive is Microsoft's cloud storage solution, integrated into Windows and available on various platforms, allowing users to store files and directories in the cloud, synchronize them across devices, and share them with others.
The particular role of the `FileSyncShell64.dll` file is to serve as the "Microsoft OneDrive Shell Extension" for 64-bit systems. In the context of software, a "shell extension" is a piece of code that extends or enhances the capabilities of the operating system's shell, which, for Windows users, is predominantly the Windows Explorer. This means that this DLL provides the necessary functionalities to seamlessly integrate OneDrive's features right into the Windows Explorer interface. When you right-click on a file or folder in Explorer, you might see OneDrive-related options, or you might observe OneDrive-specific icons indicating the synchronization status of files and folders. These integrations are made possible, in part, because of the functionalities housed in this DLL.
For users, the visible features and options brought about by this DLL make the interaction with OneDrive more intuitive and integrated. Instead of having to open a separate application or go online, users can manage many of OneDrive's features directly from the familiar environment of Windows Explorer. If there are issues or errors related to this DLL, it could disrupt the smooth integration of OneDrive into Windows Explorer, possibly affecting the visual cues and right-click functionalities associated with OneDrive. In such cases, reinstalling OneDrive or updating to the latest version might help in resolving the issues.
