Zbox is a zero-details, privacy-focused embeddable file system. Its goal is to help application store files securely, privately and reliably. By encapsulating files and directories into an encrypted repository, it provides a virtual file system and exclusive access to authorised application. Unlike other system-level file systems, such as ext4, XFS and Btrfs, which provide shared access to multiple processes, Zbox is a file system that runs in the same memory space as the application. It only provides access to one process at a time.
