    Unaccounted for Dell Laptop Hard Drive space on C: drive SSD


    I have a Dell Inspiron 3793 running Windows 10 Home version 1909. The C drive is a 256GB SSD, and I am noticing a bunch of unaccounted for hard drive space (see pictures below). Drive properties show 163GB used, but when I select all the files they only total to 94GB (69GB unaccounted for). If you look on the WinDirStat listing below, there is a 32GB file labelled "<Unknown>". What is going on? What can I do to free up the space?

    Once C:\Windows & its subfolders are involved, File explorer is useless at providing sizing data.

    Your WinDirStat is probably better.

    I use JamSoftware's Treesize [free]. This is definitely better than File explorer in this respect.
    - Perhaps Treesize will also shed more light on that Unknown entry you had in WinDirStat?

    1) In the left lower corner search type: storage > click storage settings > click free up space now > check all boxes > click remove files

    2) In the left lower corner search type: clean > click disk cleanup > check all boxes > click clean up system files > click ok > click delete files

    3) As Try3 commented > post images using treesize

    4) This is a tutorial to free up space:

    I did the drive properties disk cleanup along with cleaning up system files. Here is TreeSize listing:

    You need to expand the tree for your Windows folder, it shouldn't be as large as the 39GB TreeSize shows yours to be. Typically after cleaning up system files I'd expect it to be less than 20GB, as mine is....
