Memory usage at C:/ is very high


In majority of cases, these mysterious large number of files is down to :-

1) lots of restore points - if so just delete them from settings menus and put a limit on how much can be stored,

2) backups from something like File History Backup

3) backups from some other app like Apple backing up photos on pc.

I use Treesize to see what is stored. It is better than tool you used as it shows individual files, so you can usually work out what is storing the files.

Also Treesize is great at deleting such files.
Most files is DFOptmizer_ .......Bin there are a great amout of this kinde o files!!! What does that mean??? How can I send a copy of these files!!

None of us have yet suggested using your Disk Cleanup utility to delete old files on your C: Drive.

Steps:
1. Search for Disk Cleanup
2. Open the app as Administrator
3. Check all the boxes in both views
4. Click Run
5. You should have a lot more space on your Drive after it's completed. Let us know.
Disk cleanup rarely helps in this situation.

This could be the reason.

Do you have a program "defraggler" it may be part of CCleaner.

As long as you uninstalled defraggler the next step is to manually delete all those DFOptmizer_ .......Bin files off of your "C" drive. Then empty the recycle bin. Reevaluate free space on "C", and see whats left as free files on "C"
