A cloud storage system receives information associating a user's cloud storage account with a network service account associated with a service provider. The cloud storage system identifies files associated with the network service account, retrieves metadata associated with the files, and provides a list of the files and their associated metadata to the user. The metadata stored by the cloud storage system may indicate the context of the identified files within the network service account. In response to a user command, the cloud storage system may store one of the identified files in the cloud storage account, and may continue to provide the content of the stored file within the network service account even if the stored file is deleted from the network service account.
