does it need to have a service running at all times in order to work, like most defrags I know (PerfectDisk, Diskeeper, etc)?

No, its a standalone program.

Actually, this is a very nice utility that does a better job than any other free defragger I have tried.
Let's face it, MS has never provided a very good one and this beats the Windows built-ins hands down.
The fact that you actually get a PROGRESS update is 100% improvement and it's pretty fast.

BTW, the author should have said that it is a "powerful Open Source defragmentation tool for Windows NT-based OSes or something similar. In case you don't know, 2000, XP, 2003 and Vista are all NT-Based operating systems. As opposed to "Windows 95-Based" like 98 and ME were.

Oddly enough, NT 4.0 is often excluded like this. I'm sure some code monkey can tell us why, but I have seen quite a few cases of this kind of mixed up OS support. And yes, there are (unfortunately) many thousands of businesses still running on NT 4.0.

People who still use NT 4.0 I would imagine. What, you didn't think there were any? Besides, as NT 4.0 did not ship with a defrag utility of any kind this would be of the most interest to those users.
