    145gb Missing Hard Drive Space due to System & Reserved


    Hi , my problem is i am missing 145gb from probably old windows 10 upgrade files in System Files .

    i am running Windows 10 Pro 64bit Version 1903 (OS Build 18362.356). Original OS was a clean install on a new pc and a Samsung NVme 500gb ssd around mid-February 2019 , so no Windows.old file. I have also deleted windows.edb indexing file which i had moved to D: drive and was around 70gb , so this 145gb must be something else. I have disabled hibernation , i have deleted all restore points and set system protection to minimum size (also tried disabling-turning off it just in case) , i keep 4gb as virtual memory

    i have tried all the tips you have recommended on similar issues (Dism.exe /online /Cleanup-Image /StartComponentCleanup ,sfc /scannow , Dism.exe /Online /Cleanup-Image /RestoreHealth , sfc /scannow , Dism.exe /Online /Cleanup-Image /StartComponentCleanup /ResetBase) and still nothing happen. Just before i wrote this msg i tried turning off indexing and search properties on all my hdd's still the problem persists

    WinDirStat shows 75,3gb should be my total C:\Drive usage , then a 7-8gb system files + 4gb virtual memory + 4,5gb system protection should be the typical usage. What can i do to avoid to fresh windows install ? i have tons of vst installed and folders set up just as i wanted so i can get some work done , it would really save my life if you can give me a solution without having to do a clean re-install. Thank you all

    So am I. Your 'System files' in 'System & reserved' is ridiculously large at 145GB, mine is one tenth that size.

    I note that your WinDirStat shows System Volume Information as containing 0 bytes and 0 folders. That is unlikely to be true, it will always contain a few files and folders.

    There are some 3rd-party apps that will also store data in System Volume Information, I suspect one of them may gone 'rogue' and written about 130GB into System Volume Information. Acronis True Image is one such app that has been guilty of this in the past, see this post:

    How do I delete files on system volume information?


    I have found in the past that TreeSizeFree when run as administrator can see inside System Volume Information....

    ... while WinDirStat can't. Here they are, side by side, looking at the same C: drive. In particular, look at System Volume Information, highlighted in both. WinDirStat says it's empty, TreeSize shows the files and folders it contains.

    Yep - Treesize will also handle long directories better when Windirstat just gives up and lumps every thing as unknown files.

    Definitely superior.

    both of you where right about treesize and thank you

    now i must search what this C:\Windows\System32\config\TxR (127,1gb) folder is !!

    from a quick google search im doing now i am seing it is the REGTRANS-MS Files eating space, will post a solution if i find one since from what i've seen many have similar missing hdd space issues so this might help them

    *edit

    ok from what i found https://support.microsoft.com/en-us/...search-service

    it is safe to delete all .regtrans-ms and .blf files in the C:\Windows\System32\config\TxR folder , so i unchecked hide protected system files in Explorer options and with administrative rights was able to go into the folder and delete them all except for 7 files (around 15mb) which where currently in use as a windows prompt told me ,

    now i have 389gb free of 465gb again !! thank you all and hope this helps anyone with similar issues

    As these files are associated with the indexing service it may well be worth running the 'Search and Indexing' troubleshooter in 'Settings > Update & Security >Troubleshoot'.

    Just in case this helps anybody, though this thread is stale...

    My same issue turned to be cause by MS SQL Server 2019 log files. Unless running with elevated permissions, WinDirStat is only able to show them as unknown files, and if I recall, it wouldn't even tell me where they were in the folder hierarchy. I downloaded a TreeSize Pro trial. It asks for elevated permissions automatically and then I could see these almost 700gb of dmp files under C:\Program Files\Microsoft SQL Server\MSSQL15.SQLDEV1\MSSQL\Log\Polybase\dump.

    Similar if I then run WinDirStat as admin, I can see the same thing.

    Even Windows Explorer is fooled and doesn't include these files in it's metrics for used space unless run as admin.

    As far as my SQL issue, that's another story, but at least I know where my disk space is going. I can provide more details if it's helpful to anybody.

    Note: WinDirStat hasn't been updated since March 2016 (according to the date created/date modified info in windirstat.exe). I no longer use or recommend it because of some of the limitations that @Bree and others have noted here. TreeSizeFree is definitely my tool of preference now as well, FWIW.
