The Developers read all threads and consider all viable suggestions, so in their proxy I thank you for yours,
However I've some queries
what would comparisons of fragmentation (a random and often shuffled temporary placement of bits)1
Individual file fragmentation occurs when a single file has been broken into multiple pieces (called extents on extent-based file systems). While disk file systems attempt to keep individual files contiguous, this is not often possible without significant performance penalties. File system check and defragmentation tools typically only account for file fragmentation in their "fragmentation percentage" statistic.
What is "value" that you mention in the last three points? What can a defragmenting programtell you about performance?
