1Situation: I know that my drive C still has 28 GB free disk space. But today, I was surprised to notice that a pop up message says I am running out of disk space. Then I checked to see drive C on My Computer and I saw it only has 100MB left. I restarted the computer and see whether I can get the free space back to 28GB. But then it gradually decreases again as time went on until it gets 0MB free space. I scanned my computer in safe mode and found no virus. And it seems that something is eating up my hard disk! Help!

In general, the system partition is not large enough. Windows operating system keeps installing update files and users will also install other applications (like restore points of system protection, caches, temporary files, etc) to the partition C. These files can eat up your free space at fast speed.

How to Fix “Something is Eating up My Hard Disk”

Solution 1: Remove programs (like large media files and so on) – a time consuming job

Solution 2: Rely on Windows’ built in tool – Disk Cleanup

Run “Disk Cleanup” via the search bar in the Start menu. In the new window, choose the desired partition, click “OK”. And the computer will start to calculate how much space can be freed up. It will scan your drives and find the files that you can safely clear. This method will give users little help.


Solution 3: Resort to Cleanup tool – CCleaner

It is used to remove unnecessary programs from the disk. And it can release disk space to some degree. The whole process to do the task may be complex for some users.


Solution 4: Extend partition

You can use partition magic to change the partition size. And it will save you time since operations will be done in several steps. Decreasing the size of other partition can help to extend the partition which is in low disk space. Here, MiniTool Partition Wizard is the one worth recommending.

Download and install the partition software to computer. Then, launch it to enter its startup interface where users should click “Launch Application” to get the main interface below.


1. Select C drive and click “Extend Partition” from the left panel to enter the next window.


2. Select an existing partition or unallocated space from the same disk to borrow free space and drag the sliding button to the desired value. Then, click “OK” to return to the main interface.


  1. Click “Apply” button to execute all changes. And after the pending operations are done, low disk space warning will not appear until the C drive gets full again.

    Four solutions are listed above, and please choose the most suitable one when something eats up your hard disk.

Tips: If you are working with Windows Server os, then you could try to use MiniTool Partition Wizard Server, the latest partition magic server to complete your task.
