File Systems (Windows Embedded CE 6.0)


Windows Embedded CE supports two kinds of file systems:

  • File systems controlled by file system drivers (FSDs)
    Because FSD-managed file systems are the preferred file system type, Windows Embedded CE includes file system drivers for a variety of file systems. In addition, embedded systems developers can create and register proprietary file systems. Regardless of the type of storage, all file systems are accessed through the Win32 file-system API.
  • Registered file systems
    The file system drivers loaded in this way include the release-directory file system (RELFSD), the object store (RAM) file system, and the ROM file system.
