Abstract: Disclosed in some examples are methods, systems, and machine readable mediums which provide for encrypted file system element containers which secure sensitive file system elements. The encrypted file system element containers are sent from a network based file storage system upon selection of file system elements for a network based file download and stored in a user's computing device in an encrypted state while the data is at rest. An application on the user's computing device may provide access to the file system elements (e.g., files, directories, and the like) inside the encrypted file system element containers according to a set of one or more access rules. Example access rules include a time-to-live (TTL) rule that deletes or causes the encrypted file system element containers to be inaccessible after a predetermined amount of time.
