The program is very good if you just select all your files, and the free space defragmentation is very effective, but the full disk defragmentation is incredibly slow. It seems just as concerned with consolidating free space as the free space defragmentation (so most of the time it is moving unfragmented files), which wouldn't necessarily be bad except that it also copies files a lot slower. With the free space defrag it was copying several sectors at a time, whereas with the full disk defrag it's copying files one at a time at a slower rate than my heartbeat (these are all small files). Also it has a bad habit of just stealing data from the next sector, so it moves the drive 1 sector at a time, copying files into that sector 1 file at a time, from the neighbouring sector until each sector is full (with the exception of when there are no files small enough to fit, then it will look ahead until it finds one). It's unfortunate that you have to use the full drive defrag to move large files to the end of the drive, because that is also a good feature.
