A system and method for managing multiple file systems on a single non-volatile memory system is described. The system may include a non-volatile memory system with non-volatile memory having first and second file systems, each associated with respective files, and having a common pool of free space. The controller may be configured to update a file system to be mounted to reflect a capacity relating to only the respective files for that file system and all of the common pool of free space, while hiding from the host the file system not being mounted. The method may include the controller only presenting a single file system and hiding the unmounted file system, or may include the controller managing multiple file systems by presenting multiple file systems concurrently.
