Ntfsresize

ntfsresize is a free Unix utility that non-destructively resizes the NTFS filesystem used by Windows NT 4.0, 2000, XP, 2003, Vista, 7, 8, 10, and 11 typically on a hard-disk partition. All NTFS versions used by 32-bit and 64-bit Windows are supported. No defragmentation is required prior to resizing since version 1.11.2. ntfsresize is included in the ntfsprogs package, developed by the Linux-NTFS project. For those that don't have a Unix system installed, it is still possible to run ntfsresize by using one of the many Linux Live CDs.
