Master File Table [MFT]

[D. Spencer Hines]

This is my Volume C Text File:

Volume (C
Volume size = 74.47 GB
Cluster size = 4 KB
Used space = 13.47 GB
Free space = 61.01 GB
Percent free space = 81 %

Volume fragmentation
Total fragmentation = 0 %
File fragmentation = 0 %
Free space fragmentation = 0 %

File fragmentation
Total files = 117,725
Average file size = 130 KB
Total fragmented files = 0
Total excess fragments = 0
Average fragments per file = 1.00

Pagefile fragmentation
Pagefile size = 1.50 GB
Total fragments = 1

Folder fragmentation
Total folders = 6,668
Fragmented folders = 1
Excess folder fragments = 0

Master File Table (MFT) fragmentation
Total MFT size = 122 MB
MFT record count = 124,448
Percent MFT in use = 99 %
Total MFT fragments = 3

--------------------------------------------------------------------------------

Fragments File Size Files that cannot be defragmented

None
-------------------------------------------

Should I be concerned about the MFT figure of 99% in use?

Should I be concerned about those three MFT fragments?

Do I need to have a larger MFT?

Thank you.

No

No. It'll grow automatically when it needs to.

Thanks.

What makes it grow automatically and where can I find reliable technical
details?

From http://support.microsoft.com/kb/315688/en-us :

After you create and format an NTFS volume, NTFS metafiles are created.
One of these metafiles is called the "Master File Table" (MFT). This
file is very small when it is created (approximately 16 KB), but it
grows as files and folders are created on the volume. When a file is
created, it is entered into the MFT as a file record segment, which is
always 1024 bytes (1 KB) in size. As files are added to the volume, the
MFT grows as required. However, when you delete files, the associated
file record segments are marked as free to be reused, but the total file
record segments and associated MFT allocation remains the same. This
behavior explains why you do not regain the space that is used by the
MFT after you delete a large number of files.
