I downloaded defraggler because i have to large disk and i can't even defragment it in a day and this program allows to defragment folders only. However i have been getting these messages:
I already closed it, but there was nothing in that section and overall fragmentation even increased. I doubt anything was defragmented. I probably try different program later.

If you don’t have 15% free space, Windows won’t be able to properly defragment the drive. Windows will only partially defragment the drive, and it will grow increasingly fragmented over time.

Suggestions:
I would try running Disk Clean-up with 'Clean up system files' selected to see if you can get that used space down any.
(The 'Windows update clean up' files in particular can be very large).
A lot of what is listed there seem to be 'Features-on-Demand' packages, are you actually using those features? If not you can remove them.
Delete any old files that you don't want/need anymore - and/or move some of the files onto another drive, memory stick, etc.
In the end though if you want to keep those files on the computer itself you will have to get a bigger drive installed, (or a second internal or external drive).
