There’s a new trend where Windows user now install Windows 10 on a solid-state drive (SSD). This drive has a relatively small capacity compared to the commonly used hard disk drive (HDD). And after using Windows 10 for a while, you face a low disk space problem.
Unknowing to you, a lot of things you are not aware of are taking over the space of your drives, like Hibernation files, system volume information, page files and Windows updates. If you stand by and do nothing about this, one day you will receive a Low Disk Space warning.

The Windows File Explorer can help you in this process because it has it a built-in.

- Enter size:gigantic in the search box is at the top right of the window and press Enter to find files that are larger than 1-4 GB.

- Delete or move the large files that will be displayed on the search result
You can also type size:gigantic to find files are from 4GB and above or size:large to find files that ranging 128MB to 1GB.
Note: Make sure you know the file you are deleting so you won’t delete a file that will affect your system’s performance.
2. Run Disk Cleanup in Windows 10
You can use the Windows Disk Cleanup tool found in Windows 10/8/7 to delete different files including temporary internet files and even previous windows installations.
To locate the previous windows installations, just go to the C: drive and locate the Windows.old folder. Follow the steps below to use the Disk Cleanup tool.

If you delete the ESD file, however, you will have a 3GB added disk space, but you will lose the Reset this PC feature.
