A couple questions -

I had last year installed an earlier version of sage. I attempted to delete it by deleting the contents of the folder C:\Users\wchen\VirtualBox VMs\

(I'm using windows 7)

Then I also uninstalled the VirtualBox VM via the control panel, and then reinstalled both via the instructions on http://wiki.sagemath.org/SageAppliance

Now after logging into the sage vm using the username/password "sage"/"sage", in the linux console under the path /home/sage, I see two folders, called "sage" and "sage-5.5". The former is highlighted light blue, whereas the latter is dark blue.

As far as I can tell, they both have exactly the same contents, and in particular each contains an executable called "sage".

What is the difference between the two?

thanks,

Under the default color settings in Linux, light blue (actually cyan) typically implies that it is a soft symbolic link, whereas dark blue implies that it is a directory. I suspect the sage is just a soft symbolic link to sage-5.5. You can verify by doing a full listing

ls -l /home/sage

It will come up like this: sage -> sage-5.5 or something similar.
