How can I partition my hard drive (so as to share files between Windows 7 and Ubuntu 12.04.1 LTS) AFTER I've already installed the Ubuntu OS on the initial NTFS hard drive (which has allowed for dual boot capabilities)?

Please post the output of these two commands: sudo fdisk -l and sudo parted -l. Also, please use code tags for readability. –  user25656 Jan 8 '13 at 16:47
