  • Patent number: 10664440
    Abstract: A computing system performs file conversion upon format expiration. A computing system evaluates a risk of expiration of a first format associated with a first format object. The computing system determines if the risk of expiration is above a threshold. The computing system identifies in response to determining the risk of expiration is above the threshold, one or more files stored in the first format for conversion. The computing system converts one or more files stored in the first format to a second format. The computing system saves the one or more files in the second format.
