Since various software has different "rules" then you will find what you noted to be true.
Nothing broken. Just one might have a rule to place big files later, the other may order by access time.
Here's a tip. Don't be like a neighbor of mine. I think the only reason they have the computer on is to run defrag.
Can anyone tell me why if I alternate between windows and diskeeper defragger, each application seems to undo the previous.
I would have thought collecting file fragments together would have achieved the same result in both applications.
What do they do so differently that running one of them still gives the other a mass of work to do.
