That's OK; Moving folders still doesn't work right if there's a lot of child folders/files/objects in it. (Seriously- it's faster for me to fire up a commnd prompt or powershell session, "net use z: \\unc_path_to_root_folder", change to the Z drive, move the folder in question, swap back to the c drive, and unmap the drive lettter.)
I sympathize.
