+/********************* Files and Storage handling ****************************
+ * This example implements all main storage and file functions of the MSG API
+ *
+ * Scenario :
+ * - display information on the disks mounted by the current host
+ * - create a 200,000 bytes file
+ * - completely read the created file
+ * - write 100,000 bytes in the file
+ * - rename the created file
+ * - attach some user data to a disk
+ * - dump disk's contents
+ *
