  1. I don't know exact since which version, but as of version 1.15.163, I believe it has a bug on how it handles non-compressed sparse file types. Defraggler still "thinks" that a range of sparse clusters actually consume physical clusters. The "$BadClus:$Bad" file is a non-compressed sparse file and this is the cause of the problem where users are seeing that file even though their NTFS volume don't have any bad cluster at all (even if it's a 6 years old drive like mine - still healthy). Other files which are the same file type may likely to suffer this bug. I suggest the Dev Team take a look at
  2. Hi, I'd like to give several suggestions regarding defragmentation efficiency and minimizing fragmentations. 1. Add an option for not to defrag "fragments whose size is greater than x mega bytes". Defragmenting large files (eg. several hundred MB or several GB) that have small number of fragments are IMO, waste of time and the result doesn't impact on data transfer rate that much. This option should apply for both drive and file based defragmentation. 2. For drive-based defragmentation, a manually editable file exclusion list should be present. These files should be treated as "breakab
