  1. Try running windirstat on the drive, it will show whats using the most space (Bigger squares= bigger space)
  2. It doesnt make sense :(
  3. what happens if you highlight artykuly as that appears to be where all the usage is, then click on a box that matches the color using the most (in your above pic, purple = mp3 files

    the percentages don't make any sense, do they... even if artykuly takes up 96.9% its still only using 7.1gb

    have you run chkdsk and/or hdtune on hdd to make sure its just not losing space from age. In my last PC my boot drive was randomly losing space and I didn't know why.
  4. Just made chkdsk and it seems to be fine

    Its ssd disk and notebook is not that old 2-3yrs
  5. So this explains the difference between 142gb and its capacity, C is on same drive. C&D are just partitions on the ssd. So what is affecting D is also a problem for C.

    try HDTune and check health tab.

    Have you run anti virus? what is on D? One way to get all the space back is to format it.
  6. Yes they are both on one drive and C & D are just partitions. I never used hdtune so dont know if it right but i think it show everything is ok :
  7. not sure if it will help but can you right click start
    choose disk management
    take a screenshot and show here.

    I have to go to sleep now but someone else might think of what I am missing.
    Front page of windirstat shows right space and yet its not when you look at the drive. How odd.
  8. Ok, Thx Mate.

    I have post earlier printscreen from disk managment,but it didnt help me anyway.

    Now i have moved this biggest folder from D to C drive and there is nothing left on D, but still i miss space on D and its keep missing :(
  9. that screen isn't disk management, it should look like

    it probably won't explain the missing space but it might. Something eating 130gb and not showing.

    I wonder if its backup - it would show in settings/update & security/backup if it were.

    if there is nothing on D you need, try formatting it. right click partition in disk management to do that. Careful not to format C by accident.

    I will look in here in morning.
  10. Ok, sorry. Here it also looks ok :

    Thx Mate.
  11. I did look yesterday, the web site hosting screenshots wasn't working so I couldn't do a lot. It is working now but I have to go out for next 10 hours so I won't get a chance to help you until then... I will look at shots again. Disk management clearly agrees with the usage but what is using all the space is still a mystery.
  12. Colif its a mystery for me also. I have move the one and only true taking space folder from drive D to drive C and that made me gain like more than 7gb, but after two days on drive D i've got 1,93gb left :( so i dont know what to do :( If You dont have any idea please write how to erase this partition D safely :)
  13. Now its 362mb on drive D :(
  14. Did you run anti virus scans as unless you have a torrent client that is keeping copies of files, I can't think of why its chewing your space.

    formatting partition won't help if its something running on C that is causing it.

    the instructions for win 10 are the same as Win 7, go here and click To format an existing partition -
  15. I'm using torrent but not on this pc, not anymore. I have etherum wallet but its on drive C in light mode.I have avg from few years- it didnt find anything
  16. i have asked for fresh eyes on this thread, hopefully someone will help us figure out what I am missing.

    if it was a hdd, I would say sectors are being corrupted and thats why nothing seems to be using the space up. But SSD don't have sectors and I don't think dying ssd would be gradual, and chkdsk & hdtune found no damage.

    nothing in the file system according to windirstat is anywhere big enough to explain the losses. That why i suggested it was backup or file shadow copy but system restore isn't normally this hungry and should have shown up in windirstat as a yellow box marked unknown... it didn't.

    Run malwarebytes and see if it finds anything.

    Do you use onedrive?
  17. Nope i dont use onedrive and never used malwarebytes but it showed nothing.
  18. check system restore, see how much space allocated to it (probably on C anyway but worth a look).
    run defrag (even though they say not to on ssd, it won't hurt - win 10 runs it once a month anyway)
    could it be steam updates?

    is hdd activity normal? Normal should be 0, any processes constantly using space?

    Try booting into a linux live USB and see if it shows the contents of the drive. I don't get how its not showing in windirstat. There is a huge discrepancy between front page showing size of drive and space used, and what actually shows in the directory structure. Something is missing

    not a virus
    not maleware
    not ssd - unless 2 tests are lying
    not torrent (Did you delete it before and remove folders?)
    not page file (as it should show in windirstat, I assume its on C partition)

    running out of ideas besides a format of the partition. If that doesn't fix, need to look at what programs you are running.
  19. i have run defrag.

    Now it gave back some space to D drive : 2.49gb free but its eating free space on drive C :/

    Hmmm now when i looked up in task manager there are a lot of programs running and eating a lot of resources with name :

    Report problems with Windows-32bit(i have windows 64-bit) from task manager i go to resources manager nad there it is again its called WerFault.exe very strange.
  20. 1. Did you run WinDirStat as Administrator?

    2. Do you have some capture thing going on?
  21. Try this to fix werfault.exe

    right click start button
    choose powershell (admin)
    type SFC /scannow and press enter
    once its completed, copy/paste this command into same window:
    Repair-WindowsImage -Online -RestoreHealth and press enter
    SFC fixes system files, second command cleans image files, re run SFC if it failed to fix all files the 1st time, and restart PC

    The werfault.exe is used for Windows Error Reporting. It is a feature that allows Microsoft to track and address errors relating to the operating system, Windows features, and applications. It gives you the option to send data about errors to Microsoft and to receive information about solutions.
  22. Yes i have run WinDirStat as admin but it didnt show anything. Like ther's no 142gb on my D drive:(

    Capture thing? No im not doing anything at the moment.

    I have stopped WerFault but didnt get any memory back, maybe WerFault have taken memory space?
  23. I have switch of this WerFault, but now i have made what You told me to.It didnt need restart so it has not made it.
  24. Colif the link from microsoft was great.I have download TreeSize and it shows where is my all disk space, check it guys :

    Should i delete it?
  25. So we can see it... wonder what it is?

    it looks like its been made by windows, as i seen file descriptions like that in windows before. wonder if its windows updates though 28.4gb is way too big... did you get an update that restarted PC a few times recently?

    try running disk cleanup on the partition -

    can you expand the name column to show full file names? wonder if it shows file type
  26. I did disk cleanup on this partition and it didnt help :(
  27. I found something like that on some forum:

    Some shadow storage??
  28. Best answer
    It helped!1. To see the space allocated and used for SVI:

    – Open Command Prompt with “Run as Administrator” option

    – Type in: vssadmin list shadowstorage

    – You will see Used Space, Allocated Space and Maximum Space for SVI

    2. To see the restore information stored therein:

    – Use in the same console command: vssadmin list shadows

    3. To resize the maximum allocated space:

    – Type in command: vssadmin resize shadowstorage /on=[here add the drive letter]: /For=[here add the drive letter]: /Maxsize=[here add the maximum size]

    – E.g., vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=4GB

    – You will see a prompt confirming resize done

    – You can check the status again using the command discussed in point 1 above

    4. Just to get rid of the space already consumed, but sticking to the same size of max-size as before:

    – Do actions as per point 3 to set the max-size t, say, 1GB

    – If you check now, most likely you’ll see that used space is now 0KB

    – Do the resize again and set it back to what it was before

    – Check your disk space availability in Windows Explorer, you should see the reclaim is done!

    I would go one step further and designate a volume for your restore points / shadow copy / pagefile so as to contain it to that space and not use space on the other partitions. Many factory default setups have system restore already configured and set on a certain pre-created volume.

    Another Disk Space free-up option is if you have lots of RAM you can also free-up space setting the page-file to set max size of 8GB so that you are not using system managed which can in some situations be a huge amount of space on the System drive in many cases about 1.5X RAM GB.

    In the case of laptops another option is not to use hibernation which can use up to your max RAM+pagefile of Disk space for the snapshot of your Laptop operations.
  29. Thank You Guys for help cause i know that without your help i would not make it! hope that it will also help somebody else.
  30. shadowstorage is tied into System restore, I am sure I suggested you look at what your current maximum is.

    I am glad you worked it out :)
