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, and 10 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.
- Full compatibility with all known NTFS versions from Windows NT 3.1 to Windows Vista
- Checks internal structures for errors
- Will work in various difficult situations:
- Will refuse to run under certain conditions:
- When the volume is flagged dirty, that is marked for Windows to run CHKDSK at boot. The—force switch will over-ride this
- When Windows is hibernated on the partition
