Some people tried to delete files, uninstall program or other methods, so the Low Disk Space notification is disabled, but it pops up again in near future. You need a solution to solve this problem completely, generally speaking, there are 3 steps.

After freeing up space with Disk Cleanup, you’ll get more free space in C drive. To the computer that never or have not done this step for a long time, you may get over 10GB free space. But this is not enough. These free space will be eaten up quickly by new junk files. You need to add more free space to C drive.

Step 2 – Increase size of C drive

All disk drives are allocated while installing Operating System or by OEM manufacturers, but you can change the size of these partitions without reinstalling.

This step is very important especially to the computer that C drive is created small. If you use a 16GB iPhone, you have to delete files and clean up very frequently, but if you use a 256GB device, you won’t encounter the space issue for a long time.

So extend C drive as large as possible, any existing Unallocated or unused space inside of other drives in the same disk can be moved into C drive.

The larger C drive is, the less probability of low disk space. But new junk and unnecessary files are produced continuously, so you need to run Windows Disk Cleanup monthly to delete these files, then free space and files will achieve a balance. In addition, you’d better consider the options:

  1. All programs are installed to C drive by default, you’d better manually change to other drive such as D.
  2. To the programs that have been installed in C drive, change the output location to other partition.
