please explain Folders VS NTFS:Include Only

[8legged]

I was configuring everything for the first time, and settings confused me:

I)
Options -> NTFS
I added my D: (ntfs drive)
D:\

Options -> NTFS -> Include Only
I only wanted a single dir (and all children) in this drive to be indexed so I added it to Include only.
D:\MyDir

Then I found another option:
Folders (List of folders to include in everything Index)
is ths different? How? does one use the MFT and the other simple file scanning? and if this is the case what happens if i set folder in both ntfs options list and folders list? which one is used?

What is the difference between selecting folders in the ntfs section and selecting them in the folders section?
does one of themust MFt and the other doesnt?
which one takes pecedence if both are used for the same folder?
IS this only for showing result or is this for storing in the index?

I created my first post and then couldnt find it to edit some stuff, soi created it again, and again could not find it, i know they have to be reviewed but there is no way to know if they are under review or i never clicked submit!

NTFS indexing uses the MFT which is generally much faster than folder indexing.
If you are only indexing a single folder, folder indexing might be faster.

NTFS indexing uses the USN Journal to detected changes.
All changes will be detected.

Folder indexing uses ReadDirectoryChanges.
ReadDirectoryChanges can miss changes and some change events are incomplete.
A rescan will pick up any missed changes.
A daily rescan is recommended for folder indexes. (Set under Tools -> Options -> Folders -> Update daily (default))

if this is the case what happens if i set folder in both ntfs options list and folders list? which one is used?

Both folders are added.
You will end up with duplicated results.

Thank You very much.

If you are only indexing a single folder, folder indexing might be faster.

well my single folder has hundreds of subfolders, and thousands of files, I suppose in my case using MFT is faster right?

NTFS indexing will most likely be faster.

Note: The entire MFT has to be scanned, even if you only want to index one folder.
