What feature allows users to maintain the same files across multiple devices under a single account?

File synchronization is a feature that enables users to keep the same files updated across multiple devices linked to a single account. It works by automatically syncing files to a cloud service or server whenever changes are made, ensuring that all devices have access to the latest version of the files.

This process is particularly useful for individuals who work on multiple devices, such as a desktop computer and a laptop or tablet, as it eliminates the need to manually transfer files between each device. Users can edit a document on one device, and that change will automatically reflect on all other devices connected to the account.

Virtualization refers to creating virtual versions of devices or resources, such as servers or storage, but does not relate directly to maintaining files across devices. Remote access allows users to access a computer or network from a different location, but again, it does not specifically address file synchronization. Data backup involves creating copies of data to prevent loss but does not guarantee that those files will be the same across multiple devices in real-time.
