    Abstract: A system is described to create and transmit a streamable ZIP file container. The streamable ZIP file container contains stream metadata, files, and a central directory. The stream metadata, files, and central directory can be saved in a contiguous stream without any intervening bytes. When the streamable ZIP file container is read by a client device that supports streamable ZIP file containers, the client device can exit the data stream without receiving the central directory. Interruptions during transmission of the ZIP file container can be resumed.

    Abstract translation: 描述了一个系统来创建和传输可流式的ZIP文件容器。 可流式ZIP文件容器包含流元数据，文件和中央目录。 流元数据，文件和中央目录可以保存在连续的流中，而不会有任何中间字节。 当可流式ZIP文件容器由支持可流式ZIP文件容器的客户端设备读取时，客户端设备可以退出数据流而不接收中央目录。 可以恢复ZIP文件容器传输过程中的中断。

    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for erasing user data stored in a file system. The method includes destroying all key bags containing encryption keys on a device having a file system encrypted on a per file and per class basis, erasing and rebuilding at least part of the file system associated with user data, and creating a new default key bag containing encryption keys. Also disclosed herein is a method of erasing user data stored in a remote file system encrypted on a per file and per class basis. The method includes transmitting obliteration instructions to a remote device, which cause the remote device to destroy all key bags containing encryption keys on the remote device, erase and rebuild at least part of the file system associated with user data, and create on the remote device a new default key bag containing encryption keys.

    Abstract: Disclosed herein is a technique for managing disk space in user devices. A disk space manager is configured to manage the disk space by requesting clients running on the user device to free up disk space. The clients receive the requests and respond to the requests by deleting their own data to free up the requested disk space.
