## What it is
A command-line tool that converts NTFS filesystems to Btrfs in place, on both Windows and Linux, keeping the original image as a reflink copy for rollback. It is the NTFS counterpart to btrfs-convert.

## Use cases
- convert ntfs partition to btrfs without reformatting
- in-place filesystem conversion windows
- migrate windows drive to btrfs
- convert ntfs to btrfs on linux
- undo ntfs to btrfs conversion keeping rollback image

## When to choose
- You want to switch an existing NTFS volume to Btrfs without backing up and reformatting
- You use WinBtrfs on Windows and want native Btrfs volumes
- You need a btrfs-convert-style tool for NTFS on Linux

## When to avoid
- Converting your boot drive or a drive with an in-use pagefile
- You need a guaranteed-safe, production-critical conversion - filesystem conversion always carries risk
- You want conversion to filesystems other than Btrfs
