    A weird case of missing system files/folders


    Weird case.

    I have 2 identical laptops, running Windows 10 1511 Pro and identical
    software. I keep all data always in sync via OneDrive -- use one in the
    office and one out.

    The only difference between them is that one runs 10586.679, which was
    freshly installed by me; the other 10586.494 upgraded in place from
    Windows 7 by previous owner.

    When I compare the contents of drive C:, both have the following:

    Perflogs
    Program Files
    Program Files (x86)
    ProgramData
    temp
    Users
    Windows
    AMTAG.BIN

    but the 679 also has the following:

    swapfile.sys
    pagefile.sys
    hiberfile.sys
    BOOTNXT
    bootmgr
    System Volume Information
    Recovery
    Output
    $recycle.bin
    drvtmp
    Documents and Settings
    boot

    It seems to me that these are required files and should be on both systems.
    Yet one laptop seems to run without them.

    Does anybody have any idea what's going on? Should I worry? Anything I
    need to do to fix?

    I imagine that in the second one (679) you have "hide protected operating system files" unticked in options.

    Show Hidden Files, Folders, and Drives in Windows 10 | Windows 10 Tutorials

    The swapfile.sys etc are there in both you just aren't seeing it in the first as it is a system file and it defaults to hiding it.

    Thanks.

    Nope -- the "Show system files" is checked.

    "Show system files" is checked.
    and how about Hidden Files? Is that checked? As the files you mentioned are all hidden.

    Perhaps try to open an elevated command prompt on the .494 one and try dir c:\ and then dir /a c:\

    The /a switch means "show all" so you should (hopefully) see the "missing" files/directories.

    You should see a difference like this:
    Code:
    C:\Windows\system32>dir c:\
     Volume in drive C is Windows
     Volume Serial Number is 96FA-E594
    
     Directory of c:\

    Thanks.

    Yup, they did appear.

    So the question is what is the setting that makes them appear on one and not the other?
    So that I can hide them on both.

    There are two settings - turn off "Show Hidden Files" and turn on "Hide Operating System Files". Both are explained in the Tutorial above.

    Like this:

    Ah, I should have figured it out. Thanks.

    Just did that, but there are still several that stay visible that are not in the other:

    Output
    drvtmp
    temp
    boot

    Any idea what they are and whether they are required?

    OK, three were empty and I just deleted them.
    One is for an application.
    So everything is clear. Thanks for all the help.
