"Great app,unique features,works on <5% free space, too."
The folder it creates in C:\Program Files\ can be copied to and run from a flash drive.
It allows a freespace defrag. This is anot a run of the mill option.
Requires only 5% free space to work with.
Doesn't touch the MFT.
I've cleaned up 4 machines with it and it seems to work great.
I liked that I could install it to a local machine, and carry around the folder it creates in C:\Program Files\ and run it from a flash drive.
Another big bonus is that it allows a freespace defrag. I seemed to get the most bang for my buck, so to speak since it is free, by doing a full drive defrag, then a full freespace defrag, then a full defrag again.
It is especially effective on those files bigger than 2GB which Microsoft can't seem to defrag whatsoever.
It also does a great job on full disks, requiring only 5% free space to work with.
I only wish it could work with the MFT, too.
Did I mention it is free? It is just an awesome tool for non-profits like us who can't afford the $35/seat that the commercial offerings seem to think the function is worth. I've got trial versions of these commercial packages, and this works better anyhow.
