Vista - User folder not Recognizing Folder Location

Vista Business Admin Username = "BOB" on an updated, freshly installed 32-bit PC.

Problem:

I partition my hard drive into a system "c:" and a data partition "Z:". I moved my music, pictures, and videos folder from the user "BOB" folder located on c: to my data partition "z:" by the right-clicking > properties > location method.

The c: drive has no extra room for any more data while the z: drive has plenty.

But when I try to move a large music library folder from my passport to the music folder on z:, I get a "There is not enough space on BOB. You need an additional 2gb to copy these files" message.

Things I have DONE:

I have tried this with all 3 folders that I have moved to the z: drive. No difference
I checked both the explorer bar and the location tab in the properties dialog and they both show that the folder is in the right location "z:"
I have tried changing the ownership of z: (and all of its subfolders) from SYSTEM to "BOB" and redoing the folder movement again via properties>location method but no change.

The only way I can move the large files to z:/music is by clicking
computers > z:> music. Clicking on start menu>BOB>music will not work.



The PC is thinking that the MUSIC folder is in the c: drive only when moving files to the MUSIC folder. Moving small files to MUSIC is okay since the c: drive has enough space. But of course, the files when done moving is actually in z:



Please help.
