Abstract: Methods and apparatus for deleting a plurality of documents associated with an electronic document review application are disclosed. For example, a user may specify a subset of documents that the user would like to review in an electronic document review application. The system executes a query to construct a document container that lists the plurality of documents and automatically downloads the documents and associated metadata to the portable electronic device. The system then periodically compares a current time associated with a local clock of the portable electronic device with an expiration time to determine a comparison result (e.g., is a certain document container more than 30 days old?). The system automatically deletes the document container and any of the plurality of documents that were downloaded to the portable electronic device when the comparison result is indicative of the plurality of documents expiring.
