NTFS file system utility

## NAME

**ntfs.util** – NTFS file system utility

## SYNOPSIS

**ntfs.util** **-k** *device*

**ntfs.util** **-m** *device* *mountpoint* *mountflag1* *mountflag2* *mountflag3* *mountflag4*

**ntfs.util** **-p** *device* *mountflag1* *mountflag2*

**ntfs.util** **-u** *device* *mountpoint*

## DESCRIPTION

The **ntfs.util** command supports the mounting, probing, and unmounting of NTFS file systems.

Options:

- **-k**

  Get the UUID key for the NTFS file system at *device*.

- **-m**

  Mount the NTFS file system located on *device* onto *mountpoint* with the flags *mountflag1* *mountflag2* *mountflag3* *mountflag4*.

- **-p**

The *mountflags* referenced above are:
