After managing to resolve other issues of the installation steps, I now face this. I can't see the two files in the Packages folder. Bu I can see themfrom the host:
[Oracle@linux ~]$ su root
Password:
[root@linux Oracle]# mount -t vboxsf DAPfiles /home/Oracle/media
[root@linux Oracle]# cd /home/Oracle/media
[root@linux media]# ls
Linux Oracle Packages
[root@linux media]# cd Packages
[root@linux Packages]# ls
packages.zip
[root@linux Packages]#
Regards

My apologies ,I have just resolved this issue by first unzipping the folder then the two files got listed.
Thanks
