Replicating files among Grid nodes is due to the distributed nature of the Data Grids where geographically distributed data lead to access latency. Most replication methods either monitor the popularity of files or use complicated functions to calculate overall cost whether a replication decision or a deletion decision should be issued. However, when the replication decision is executed, the popularity of the files had changed and may have already given impact on access latency and resource usage. This paper proposes a predictive file replication strategy that forecasts files' future popularity based on their characteristics on the Grids
