What is filling up my C: drive and how can I stop it?
Question by Alan Trinder /
Ads by Google

I have read a number of replies on similar problems but none seem to really help me. My C: drive is being used up. Initially it had 50gb, I have had to add a further 20gb by moving partitions and it has managed to fill that space as well. I run Ccleaner and Glary utilities regularly. Windows says it does not need defragging.
My questions are;
What is filling the space?
How do I get rid of it?
How to stop it in the future?

  • binary man

    You should run Directory Report in administrator mode
    It will show you the size of all files/folders - including hidden ones
    This is something that other disk scanning programs cannot do

    Hi all, many thanks for the lots of help you have given me.
    The problem isn't system restore, that is disabled. I have now downloaded a very useful suit from Ashampoo called Winoptimiser. this includes a very simple hibernation fix that gave me back 2gb so I am getting there, my thanks to Avish Kansakar for that lead.
    I feel this will keep me largely out of the wood. I am left with one main puzzle, I use a programme called ACDSee Pro 5 for filing my photos. It is a great programme, very quick. The photos are on volume D but there seems to be about 15gb of thumbnails etc it has created on the c drive so any hints on this welcome

    • Avish Kansakar

      You are welcome. I used to use the acdsee program but that was years ago. I would suggest you delete those thumbs on c drive and maybe use a program called picassa. Its a photo viewer/filer and you can do some editing on it as well. Give it a try in my opinion.

    disable system restore (you will get an option to delete all check points ,delete them) then again re enable it

    These tools might help you track down what's eating all of your space:


    If you're using Windows 7, however, a 50 GB drive will fill up quickly. Sad but true.


    Use Space Sniffer.....!

  • rimaz nazeer

    Use Space Sniffer to find out what's filling up and remove all the things like what you don't need,like hiberfil.sys...etc http://www.uderzo.it/main_products/space_sniffer/
    Its Free

    System restore uses up a lot of space and so does the paging file,do a DiskCleanup

    Start -> All Programs ->Accessories -> System Tools -> Disk Cleanup.
    Disable System restore if its of no use to you or limit the amount of space that has been allotted

    You could also bring down the size of the paging file by limiting its allocation

    And also regularly defrag the drive if you want to prevent it in the future

    A good Defrag Software is : http://www.iobit.com/iobitsmartdefrag.html

    Also Clean your Pc Regularly using CC CLeaner : http://www.piriform.com/CCLEANER

    Hope it helps

    Hi all, with respect to system restore, if I go to this via control panel i see the message "no restore points have been created on your computer system drive" I take it this means it is not system restore?

  • Avish Kansakar

    There is this program called Ashampoo WinOptimizer. It has a useful tool built into in called the drive space explorer. Will show you exactly which folders and files are taking up the space. I found this tool much more easier to use than any other out there and the results it gives out is easy to read as well.

    Turn off hibernation. That'll free up a bit of memory from your hard drive. Depends on your ram too. If you have like 6gb of ram, then turning off hibernation will free up to about 6gb of ram. If you have 16gb of ram, it'll free up to 16gb of memory. Another thing you could do is get yourself another hard drive (Internal or external) and move all your music, videos, and such to that hard drive.
