    What is causing my HD to "add 5 GB "every day on Windows 10 system?


    I am baffled and need your help. Running Windows 10 Pro build 1903. My boot drive is a 512GB Samsung 970Pro NVMe. My Windows is a legal copy (not hacked version).

    I noticed that starting about 2 months ago (even while running previous Windows 10 Pro 1809 build) that every day that I use the PC, about 5GB of mysterious data gets added to my hard drive. So basically at this pace, I will run out of space on my system drive (C:) in about 20 days. Upgrading to build 1903 hasn't helped.

    I have tried figuring out which program may be doing this but so far no luck. I have tried to do a Windows Explorer "Search" for recently used/added files 512MB+ or 1GB+ but nothing looks out of ordinary. I have cleaned out the C:\Users\AppData\ Local\Temp and C:\Windows\Temp directories but that didn't help.

    There must be some logging file or something likewise that is causing this behavior. I have run Malware Bytes and Kaspersky KAV virus scans (on all my drives) and they both come up with nothing. Otherwise, my system is running fast and there are no issues at all.

    Can someone give me some other ideas of how and what to look for?

    Hello, mystiky -

    Welcome to WTF!

    I see that you have posted this question around, lol, so here's what I would do...

    Download and install this free and trusted program:

    TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs

    I recommend that you run it as Administrator so the program can access and return as much information as possible about your SSD usage.

    Please post back with your results after 48-72 hours. So perform an initial scan and another after 1-2 full days, then compare.

    Alternatively, you can also use this great program (not free) but a 30 day trial:

    Download Beyond Compare Free Trial

    Thanks.



    BTW - An SSD is not the same as an HDD, so please be careful. Your boot drive is an SSD.

    update...


    Good day. As promised, I now have the updated view of drive C: . I will post the general screen shot from September 3 and compare it to September 6.

    September 3:



    September 6:


    As one can see, my drive went from 339GB used to 345GB used in 3 days. The Program Files (x86) increased by 1.5GB but the real difference is System Volume Information folder, which went from 25.3GB to 30.1GB.

    Sorry for not to having the September 3rd System Volume Information sub-folders folder tree opened, but at least I did it for September 6 version.

    Any ideas what is going on? Please tell me if you need any other subfolder trees opened, so we can again compare in like 3-4 days.

    Thank you for trying to help but it's getting silly as I am going to run out of space soon...

    Well, I had a similar problem with my C drive always creeping up with more data. I used the TreeSize free program (excellent program by the way) and determined exactly what Mystiky discovered. The System Volume Information folder was growing almost on a daily basis. Turns it it was the accumulation of system restore checkpoint files. After using Ccleaner to delete all but the last checkpoint, I've recovered almost 10Gig of space. Thanks to Compumind for the tip.

    System Volume Information is where your restore points are held. Your big files there have names that are typical for restore points. You should be able to recover the used space by deleting restore points. Automatic restore points may be responsible for eating up your disk space. You can adjust the frequency of automatic restore points, or even turn off their automatic creation. You can also set a maximum limit for the space restore points can consume.

    Yep, it was System Restore that was doing it! I changed it to only use 15GB and immediately I got almost 15GB back.All good.Thank you everyone!

    Yes. And that's what I wanted to prove. 15GB is too much. The SVI folder is usually of no significance, unless it System Restore reaches a certain threshold depending on how you configure it.
    In your case, @mystiky, I would suggest the following now that we definitely know what it is:

    1) Rather than turning off System Restore, prune through your SSD and see what you don't need, especially browser cookies, cache and temp files, old programs, leftover installs, etc.
    2) Purge System Restore and reboot. Set it to 1% and manually create your own System Restore point.

    Bottom line is that you will need to run leaner on the SSD boot drive, so that it is not an impediment.
    You can change the Collection Frequency as @Bree correctly pointed out above but I don't recommend it.

    Try to have your system with at least 5GB available at all times. If you have multiple drives, save most of your data, if possible, on them.
    You can also compress the boot SSD, but this will result in a performance penalty and you probably don't want that.

    Enable or Disable NTFS File Compression in Windows

    You can also compress Files and Folders...

    Compress or Uncompress Files and Folders in Windows 10

    Perhaps a SSD upgrade is in order?

    The end strategy is up to you...

    Take care!
