Which service allows users to store files remotely and access them from any Apple device?

The service that allows users to store files remotely and access them from any Apple device is iCloud. iCloud is integrated into Apple’s ecosystem, providing seamless synchronization across all Apple devices, such as iPhones, iPads, and Macs. This means that when files are saved to iCloud, they are automatically updated and accessible on any device that has the user signed in with their Apple ID.

Additionally, iCloud supports a variety of file types, including documents, photos, and backups, enhancing the user experience by simplifying the management of data across devices. It also features collaboration tools, allowing multiple users to work on documents simultaneously, which is particularly useful for family and team projects.

Other services like Google Drive, Dropbox, and OneDrive offer similar functionalities but are not as tightly integrated with Apple's operating systems, leading to a less seamless experience for users within the Apple ecosystem.
