Fast update fragments files?

[wimdelange]

I did a slow optimize with version 4.1.2. After that I did a fast update, just curious. To my surprise, fast update started fragmenting some files? Probably due to the fastfill in this part of the script:


FileSelect
    not(
      Size(50000000,0)
      or (LastAccessEnabled(yes) and LastAccess(,1 month ago))
      or DirectoryName("$RECYCLE.BIN")
      or DirectoryName("RECYCLED")
      or DirectoryName("RECYCLER")
....
  FileActions
    FastFill()
    AddGap(UntilPercentageOfVolumeMultiple(1))
  FileEnd

Is it not a little bit stupid, to first defragment your disk with slow optimize and to disrupt this with fast update? And the comments stated that these belong together. Daily use fastupdate and once a month use slow optimize.

FastUpdate (FastFill) does not create fragments and also does no defragmenting. But SlowOptimize does both. Maybe the fragments you have seen are from SlowOptimize?

You can try FastOptimize to defragment. It is now compatible with SlowOptimize too (Jeroen will change the manual with the next release).

As Darlis said, FastUpdate does not create fragments, so what you observed must be something else. The FastUpdate script basically only fills gaps, and makes sure all the files are in the right zone. It does not produce a fully optimized disk, like SlowOptimize does, and that's why you need to run SlowOptimize again once per month or so.

Ok, I think that I saw something, but maybe there is another explanation too. The problem is off course that the picture became more yellow, so I assumed something. But the colorisation is off course not the complete picture. Hence the zoom option. Thanks for the explanation.

Sometimes FastOptimize and FastUpdate may break files to fragments. FastFill() may break outzoned file while clear space if no enought big gap after zone exist.
