Strange problem using Defraggler


Recommended Posts

Hello together,


driven by the wish to defragment some files on my harddisk, i decided to have a look at Defraggler.


After downloading and installing it, i ran an analysis which worked wonderful! I then selected the desired files (about 5 files of each between 200 and 500 MB in size, fragments varying from about 100 to approximately 500). I then started the defragmentation.


Defraggler worked astoundingly fast - after less than ten minutes it reached the 100% mark.


Then, however, it finished saying:



"Defrag Complete


No files were defragmented."



Obviously something went wrong, but i do not know what it is. Even though the program is actively working during the defragmentation process, the result is still that it tells me that no files were defragmented.


Can you help me?

Hi jonas,

Welcome :D

You may not have enough free-space available or large enough areas available to handle files that large.


Using Defraggler to defragment "impossible to defragment" Hard Drives by using "defrag files" method.


If your hard drive is extremely fragmented with a very limited amount of free-space, you may need to just check off the last 20-30 pages of smaller files and defrag those and then try a few medium size files. You should find out that these run very quickly and make it easier and quicker to defrag larger and larger files.

Concentrate mainly on files that you know will be deleted soon or files that you use often.

We are trying to create some larger contiguous files that will free larger and larger contiguous areas of free space when those files are deleted. This will make it easier to "defrag" those files that YOU use often. This will benefit your daily PC usage immediately.


Also "defrag" any temporary files that you can like "system volume" files. Then if it is OK to do so, you can then delete them manually, the oldest one's first. This will gradually give you larger areas available to "defrag" larger and larger files. This also applies to "Temporary Internet Files".


For larger files I would recommend that you start with files approximately 50-100 MB and check off maybe 20-30 and try that. After several of these then try a few of the 200-300 MB.

Reverse the list and check off as many as you can of the files small in size but many fragments relative to their size. Do this mainly for system type files and files related to your work or areas of interest. Things that you use often. When I first did this with the smaller files then I could just check, check, on and on and not really have to consider what type of files they are.


As you do this you are going to notice certain types of files that are large with many fragments and frequently deleted like .flv files. After awhile you will start to know which types of files are the most important to "defrag". Either you are going to delete them soon or they are files that you constantly use.


If you are tight for space, then you need to consider what should be copied to backup disks or CDs or DVDs. If you have 10-15 % free space than you can get along "defragging" files until you get enough space to "defrag" the whole drive. You don't have to "whole disk defrag" often but it is necessary to eliminate as many fragmented files as possible. It is not necessary to "defrag" files like movies and such because they are usually very large. These can be copied and then deleted to give you back large amounts of disk space.


Soon you will find that you can select all the files and the defrag will run quickly.

You will find that you have fewer and fewer files to "defrag" and Windows has taken care of any "optimizing" that is needed. If you are an average PC user like me then you will find this works very well.


I always "defrag files" just prior to running CCleaner. This way when the files are deleted they are each 1 contiguous chunk regardless the size of the file. This way I am not deleting files that have more and more fragments and smaller and smaller fragments. I am deleting files that are just the opposite. I always end up with fewer but larger free spaces. I have 97,000 defragmented files in 46,000 defragmented folders with lots of available free spaces anywhere on the disk. Windows writes the clusters at the nearest available free space. I always have some free-space nearby.


When I need to do a "whole disk defrag" which is rarely, then I run CCleaner and manually delete as much as possible before hand. This makes the "whole disk defrag" quicker.


Each PC user's usage is different but I would consider mine about average.

Specialist "users" and those with large volumes of changes require different methods than the average user.


If you keep getting the messages that you first reported then you will need to follow what is required to Run Defraggler with the Debug option again.


One way or the other I hope that I have helped you and others reading this thread,
