It looks like it's all right with the program (that is, the behavior is normal though not something we would like to see ).
I was wondering some other thing. Yesterday I was defragging my sisters Laptop with Defraggler on Vista 32 bit with SP1 (SP1 was installed on RTM wersion), while I was doing full defrag, I noticed that the space on HDD is being consumed little by little. After the defragmentation I also had the problem with System Restore Files. Not only they were not defragged, it appeard that one file in System Volume Information increased in size to 8GB of data (it consumed more than 5 GB while the program was working, just before defrag I cleaned up the disk from old System restore points)! And it is only one file... I was wondering, is it possible that during this defragmentation process, Vista was doing it's own System Restore backup? The System Restore is enabled so this is reasonable answer. But did it happen because the drive was being deffraged (moving files, including system ones) or just normal Vista behavior. The drive was containing almost 29 GB of data, there were 2288 files fragged in more than 12000 fragments. All process took more than 1 hour. And afterwards, it reached 34 and a half GB. The file I was talking about is named something like "{1435afc lot of HEX 1523fbc}{12hefa another HEX cv123}" (sorry i don't remember now but i guess you know the idea).
So my question is rather simple, is this normal Vista behavior.
See you.
