Defragmentation analyzer

[genossa]

Hi, everyone!

I'm trying to create an application similar to Windows Disk Defragmenter.
It's all going well so far. Anyway, I have a question about the following
data output that Windows Disk Defragmenter produces.

Volume fragmentation
Total fragmentation = 26 %
File fragmentation = 44 %
Free space fragmentation = 9 %

Does anyone know what is "Total fragmentation" and "Free space fragmentation"
and how should it be obtained ?

Unfortunately Disk Defragmenter Help documentation doesn't provide information on this issue:(
My primary interest is not the technical aspect of this procedure (any advice, however, would be appreciated greatly), but the definition (meaning) of this categories.

Thanks in advance!

Well, I can't tell you exactly, but in general...

"Total Fragmentation" is probably a value representing the overall fragmentation status of the disk. The other two are detail lines about allocated and non-allocated space.

"File Fragmentation" probably represents the ratio of total number of files to the total number of file fragments (file system actual allocations).

"Free Space Fragmentation" is an indicator of how many disjointed empty areas there are on a disk (non-allocated).
