Extended Version History is a cloud storage feature that retains previous versions of files for an extended period, allowing users to recover older copies even after deletion or modification. Unlike standard version history, which typically keeps past file versions for a limited time, extended version history provides longer retention, ensuring users can restore lost, corrupted, or mistakenly edited files beyond the usual timeframe.

One common use case is ransomware protection and accidental file recovery. If a file is encrypted or deleted due to a cyberattack or user error, extended version history allows retrieval of a clean copy from an earlier state. Businesses and individuals benefit from this feature for data backup, compliance, and long-term project management, ensuring critical files remain accessible over time.
