Program increases fragmentation

Recommended Posts

I downloaded this set of programs a few days ago.  I ran CCleaner, then ran Defragger, as recommended.  The program initially told me that my HDD was 11% fragmented, so I ran the full Defrag.  It took over 24 hours, and when it was finished, I re-booted my program, started Defragger again and had it analyze the drive.  It tole me that the disk was 21% fragmented.  I ran the quick defrag, and when it was done, ran the CClean program again, re-booted, and ran Defragger a third time  After another 24+ hours, the program finished, and I did another analyze, with the result that Defragger told me my disk was 34% fragmented.  I tried one more full defrag, and after another 24 hour run, Defragger tole me that the defrag was complete.  I again did a re-boot, analyzed the drive again, only to have Defragger tell me that the drive was 46% fragmented.

Just for fun, I ran an analysis with a- different defrag program, and this confirmed that the drive was 46% fragmented.

I'm thinking that I am not getting my money's worth out of Defragger, which was supposedly rated as the #1 defrag program for 2020.

Anyone else experiencing similar problems?

It may be because of the size of the files themselves and the type of defrag that you are doing.

One issue is that the single word 'Defragmenting' is often inaccurately used to mean two different things, two things which are mutually exclusive.

  1.  Getting each file into one contiguous piece, rather than split across clusters. (So that they load marginally faster).
  2.  Getting all the files into as small a storage space as possible. (To give more free clusters on the disc).

The first is 'Defragmenting' and means that some clusters on the disc will inevitably have some unused space.
The second is correctly termed 'Consolidation', and means fragmenting some files to 'pack them all in' to the available clusters.

So you can have all your files in one piece each, or have them packed into the smallest space by splitting some up. - You can't have both, and which you choose depends on what you want to do.

That consolidation could explain why your files themselves are getting more fragmented each time, to 'pack them tighter' into available clusters.

Defraggler does a combination of the two by default, but for more control you can specify which one you want instead.

In Defraggler:
'Defrag Drive' will do some of both, as it sees fit to get the best result.
'Defrag Files' will make the files contiguous (#1 above).
'Defrag Free Space' (Advanced) will consolidate the files to give the most free clusters. (#2 above) - but that means fragmenting some of the files themselves.

With drives getting as big as they are nowadays whole disk defragging is rapidly becoming a thing of the past, it just takes too long. (Personally I'd call anything over hour too long)
Splitting the drive into smaller partitions/drives would obviously help as you could defrag each partition/drive as needed.

Once you start talking terabytes rather than gigabytes then it's best to just defrag the files, that's what you want to do anyway to speed up read times, and it's unlikely (but possible) that you are short of free space on a terabyte drive.

- What is the size of that drive and how much free space (in GB & in %) does that drive have ? Do you have an SSD ?

- What Defrag option(s) did you use ?

- Did the amount of free disk space go down after each defrag ? Is System Restore active ?
