    C: drive gradually losing space while computer is not being used


    Has anyone had a problem where their C: drive fills up gradually for no reason even when the computer is not being used?

    I've gone through all of the troubleshooters to free up space, but freeing up space is not my issue.

    :)

    C: drive progressively loses space


    Hello,

    My C: drive is progressively losing space the longer my computer is on. I am currently experiencing the worst example of it so far, which has prompted me to post this support request.

    • Three hours ago, I turned my computer on. C: had 32GB of free space.
    • Thirty minutes ago, I received a 'low disk space' warning. C: had been reduced to 0 bytes.
    • I moved 3.6GB of personal files to an external drive. After checking in 'This PC', however, C: showed just 2.2GB of free space.
    • At the time of writing, C: now has 1.3GB of space remaining. This will occasionally drop in increments of 50MB to 100MB. It will also sometimes stabilise for a short time before continuing to drop again.
    The only programs I have used in the past three hours are Chrome, Firefox, Foxtel Go (a streaming application), and Media Player Classic. It does not seem to matter which applications I use - if I use any applications at all - for the space to continue disappearing. Malwarebytes has not discovered any threats, either, and nothing appears to be abnormal in Task Manager.

    How can I figure out what is going on? Can anyone help, or suggest anything? This is incredibly frustrating and inconveniencing as you can imagine.

    Thank you in advance.

    Computer: Toshiba Satellite
    Processor: Intel Core i7-4700MQ CPU @ 2.40GHz
    System type: 64-bit operating system, x64-based processor
    Operating system: Windows 10 Pro

    Unallocated Space to C Drive

    Hi Travis,

    It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

    • In Disk Management, right-click on (CC: drive gradually losing space while computer is not being used :) which appears next to the
      Unallocated partition.
    • Select Extend.

    Let us know if you're able to combine the spaces after following the steps above.

    Regards.
