NSA325 v2 - Browsing with Windows Explorer

Hi,

I have had an NSA325 v2 for some time and use it to store my photos etc.  I seem to recall I used to browse the contents using Windows Explorer - by simply typing the IP Address of the device in the Windows Explorer Bar.  Now when I do it I get the Twonky Media Server which is not that great from browsing thousands of photos.

Could someone advise how I should access the disc using Windows Explorer?  Should I set up a Mapped Network Drive - if so - what path so I use?  I have shared the Photo folder and tried mapping using \\192.168.1.63\Volume1\Photo\ but I keep getting folder not found.

Any help would be appreciated.  Cheers.

Ian
