Lots of users don't know what to do because Defraggler can't defrag system restore points or NTFS metadata, and thus think Defraggler's not good since it doesn't defrag everything.
Please exclude C:\System Volume Information\, as well as all NTFS metadata you can't defrag (e.g. $MFT), from the fragmented files, and thus don't count them when calculating the % of fragmentation of a drive. And mark them as unmovable with a special color on the drive map (black, perhaps ?).
