I have looked but haven't found much.

Are there any references to the logic used in Disk Defragmentation ?

I was also wondering about the O.S.

Say a 5 meg file is deleted.

If another file less than 5 megs is added, is it "put" in the hole
left by the
file deletion ?

If a file is deleted, the space is simply marked as being writable.
The free space is reassigned as Windows sees fit and could be used by
another file 5 meges or less
or by a file larger than 5 megs with the rest of the file placed elsewhere.

If your looking for technical info, my guess is it would
vary by brand of software and could be proprietary.

Thanks, found some info here.

Based on what's here, I switched to UltraDefrag.
It's faster than the others that I have tried.
