Pirragorm Defraggler

Defragmentation Canceled.

Some of the files were not defragmented.

The operation can not be completed.

OK


---------------------------

can never fully defragment: 

a) if the file is large (Example: 900 MB)


b ) if the file contains a lot of fragments (Example 7000 fragment)

Example file format *.WAV

This problem occurs in every version, for many, many long years and has never been solved.

The partition contains a lot of free space (90+ GB), so it's not a problem. The files are not used, so this is not the main reason for the problem.

have you tried running DF with the PC in Safe Mode?

and also try right clicking that one file and just defragging it.

Normal mode, it is pointless to defragment in safe mode. Full defragmenting of files does not work. It has been, is and will continue until the developer improves the tool. 

For comparison - other defragmenters can easily defragment those files, which unsuccessfully in Defraggler.

OK, cool, just a suggestion I thought worth looking at. 

no skin off my nose.

If HDD disk defragmentation (as a data stored) lasts all day and there is still no end, this is a task that does not make sense.

Tested on multiple HDD. 3 days (72 hours) defragment progress only 6%?

You can not defraggler any large file in Defraggler. The operation can not be completed. If you use a different tool, it lasts for a whole week and is also endless.

Example: 1 file - 16,000 fragment -> it takes defragmentation 1 hour!!!

100000 file x 1 hour = 4 166.66667 days :D
