    Unknown Disk Usage


    Hi, I have a 128GB (120GB?) SSD as my C: drive and a 3TB HDD as my D: drive. I put virtually all my programs and data on the D: drive and have the SSD as a fast boot up with the essentials. Just lately, though, the SSD has been showing as nearly full: 106GB out of the max 117GB. However, when I check the usage by checking the properties of each of the main folders, the total only adds up to 71GB, leaving 35GB unaccounted for. The folder properties is set to displaying all hidden information. I have two accounts - mine and the admin, which is virtually unused and I accept this may take up a small amount of hidden info. I would try to delete unnecessary items or move any unimportant programs to the D: drive as most of them are, but the program file folders on the C: drive are relatively small, and the update folder is also small. I cannot figure out where the extra usage is. Any ideas? Matt

    :)

    Glenn, we would like to check if you are still experiencing a high disk usage on your end, if yes, we would like to ask if you can try to follow the steps below for as a workaround:

    • Go to Start menu and select Settings

    100% disk usage and memory usage

    Hi,

    100% disk usage and memory usage can be caused by a software corruption, running application running on the background and malware or virus infection.

    For us to properly isolate the issue and provide an appropriate resolution, kindly answer the questions below:

    • Did the issue happen after installing the Fall Creators?
    • Did you receive any error messages?
    • Can you send us the screenshot of the Task Manager showing the 100% disk usage and memory usage?
    • What troubleshooting steps have you done so far?

    For isolation purposes, please perform a clean boot to see if the same issue will occur. Refer to this
    article for more information on how to perform a clean boot
    in Windows.

    Looking forward to your response.
