Rob highlights about viewing, modifying, deleting files in Volume GUIDs on Hyper-V implementation that now live on this volume without a drive letter. I haven't seen much out there on how to manage Volume GUIDs so I thought it would be a good topic for the blog. I have to plug Adam Fazio for leading to some of the info I have gained on this topic.
Like a normal volume, with a drive letter, there are 2 ways to view, modify, copy etc... files that reside therein. Explore in the GUI and Command line access.
