The

.B ntfsresize

program safely resizes Windows XP, Windows Server 2003, Windows 2000, Windows

NT4 and Longhorn NTFS filesystems without data loss. All NTFS versions are

supported, used by 32-bit and 64-bit Windows.

because the program can relocate any data if needed, without risking data

integrity.

To resize a filesystem on a partition, you must resize BOTH the filesystem
|
||||
and the partition by editing the partition table on the disk. Similarly to
|
||||
other command line filesystem resizers,

.B ntfsresize
|

program doesn't manipulate the size of partitions.
|

To do that you have to use a disk partitioning tool, for example

|
||||
Generally it's a good practice making regular backups of your
|
||||
valuable data, especially before using any partitioning tools. To do so
|
||||
for NTFS, you could use
|
||||
.BR ntfsclone (8).

It's also included in the

the NTFS filesystem otherwise you won't be able to boot and

you might lose your data.

Do not make the partition smaller than the new size of
