Central Filestore & drive R:

Users who registered to access ISD services before September 2010 may be accustomed to seeing and using their R: drive under Windows Explorer or My Computer.

If you are in this category, you will have Windows files from your previously used R: drive under your Central Windows Filestore under a subdirectory of your N: drive - N:\Rdrive\

You can also access these files as if they were on drive R: though this actually just links to your N:\Rdrive directory (it may be useful to think of this as a "virtual" drive R:). Thus you have two different ways of accessing the same files - if you delete a file it will disappear from both R: and N:\Rdrive!
