Which Microsoft product allows users to store and share files online?

OneDrive is a cloud storage service that allows users to store files online and access them from anywhere with an internet connection. It is integrated with Microsoft applications and offers features like file sharing, collaboration, and syncing across devices.

Users can upload documents, photos, and other files to OneDrive, making them accessible from any device, including smartphones, tablets, and computers. This service also facilitates easy sharing of files and folders with others, enabling collaboration in real-time on projects or documents.

In contrast, SharePoint primarily serves as a platform for collaboration and content management in organizations, providing tools for building internal websites and managing workflow, but it does not focus solely on file storage. Outlook is an email client mainly for communication, while Teams is centered around team collaboration and communication, featuring chat and video conferencing capabilities alongside file sharing.
