Windows 10: Size of Win 10 Installation seems to be growing Solved

    Size of Win 10 Installation seems to be growing

    The space used on C:\ for Win 10 seems to be growing for no apparent reason. I started out with about 35 GB used and am now up to 50 GB used. I have added no software, but done all updates.

    The Windows folder size is 20.5 GB, just about what it always has been.
    I have a similar Win 10 install in D:\, it is 35 GB, and the Windows folder is 20.1 GB.

    15 GB is an awful lot of unaccounted for disk usage.

    Any suggestions appreciated.

    With 16 GB RAM, you could have a Page file and a Hibernation file each of up to nearly 16 GB = 30+GB on an x64 installation. You need to unhide system and show hidden files in File Explorer View, Options, Change...options, View

    Run a large files checker, such as Largest Files Finder - find the top 100 largest files
    to find where the biggest chunks of used diskspace are to be found.

    Hi there

    Use something like this -- displays the folders in a very convenient way so you can see what's hogging all your disk space.

    TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs

    To expand just click the arrows

    To see Hidden / system files start in administrator mode. Note FREE program. Works fine in W10 (am using build 10240)

    1st of all - thanks for the replies:

    Ran TreeSize Free - it showed a System Volume folder of 23.3 GB - just about the amount I figured to be "oversized".
    unhid all files, did a Properties check on the folder - showed 0 GB
    took Ownership of the folder, re-did Properties check - 23.3 GB - 27 Files - 4 folders.
    now i know where files have built up, what next?
    Something tells me deleting these files might not be the smartest of moves...

    Again - thanks for advcie

    System Volume folder is the same thing that System Volume information?
    Where and how do I "turn off turn"System Protection?
    Thank you

Windows 7 doesn't let you organise folders according to their size. I was hoping that maybe 10 does? Or maybe there's some complicated reason why it can't ever be done?
