Daily Blog #178: Artifacts from alternative file system drivers on NTFS Part 2

Hello Reader,
           Yesterday we went through the linux ntfs-3g driver's interaction with the MFT in NTFS. If you haven't read that you should as it explains why POSIX filespace's are the focus of today's post. Today I am going to compare the MFT my system and a test system to see how many POSIX file names are created by default so we can determine a set of rules to see if we can ascertain when a file was created by the linux ntfs-3g driver.

I parsed my MFT using mft2csv as we just added the filespace name support to v3 of anjp which we are polishing up for this months beta release. I like mft2csv and think its an easy tool to use when you just care about high detail MFT parsing. My system drive has 628,480 MFT records, its been in active use for over a year with the current install. Of those 628,480 have POSIX filespace records. So having a POSIX namespace in your filename alone does not indicate that the linux-3g driver was used in creating a file. Whats interesting here is that these POSIX filenames break down to some basic categories:

1. System files/directories like \boot and it's directories, $Recycle.bin and $Extend
2. Applications from OEMs like cygwin and hp
3. Shared libraries from visual studio, microsoft common libs and other programs
4. FTK Job work queues
5. The entire QT SDK
6. Windows directories and files
7. The user profile directories for default and public

Why is that interesting? Not a single file that I or program at my direction made in the last year as a POSIX filespace name is stored under my profile.  I want to test this on a non OEM windows install to see if the same number of POSIX filespace file names are created when you install from MS media directly.

So taking the logic one step forward, based on my limited sample set so far there should not be a user created file originally made by the native NTFS driver and using standard win32 system calls that results in a POSIX filespace file names. I am going to take this a step further tomorrow by finding which win32 calls can create POSIX filespace named files and testing this same theory against my virtual machines.
