ABSTRACT:
An application programming interface (API) module provides access to data, independent of filesystem implementation in a non-privileged user mode. A discovery volume having a filesystem recognizable by an operating system has cover files which prevent damage to data stored in an unrecognizable primary volume. The discovery volume also includes a data access API available for execution in a non-privileged user mode to render the primary volume accessible by operating systems which would otherwise find the primary volume unrecognizable.
