[NTFSINFO]
Time to free some Sysinternals tool: ntfsinfo.

To make it short, this tool dumps various information about a NTFS volume and its reserved
meta-data files

Our version comes with three advantages compared to the Russinovich's tool:
- It's FLOSS
- It works properly on NT5+ (developed with W2K3 & W7) whereas R's cannot display
meta-data files information
- It will open a volume by default if none provided

One issue so far: it doesn't work properly on ReactOS!
