Windows 10 Free up disk space
This article introduces how to free up disk space on Windows 10 (32 & 64 bit) with Disk Cleanup and additional 10 methods.
Many people feedback that system C drive becomes full after upgrading to Windows 10 or install some Updates, because there are many large files downloaded and write into C drive. In fact, system partition is filling up by many types of files continuously, so it runs out of space sooner or later if you don’t take care. It’s more likely to encounter this issue if you use SSD, because it is much smaller than traditional mechanical hard disk.
When system C drive is full, freeing up disk space is an efficient but not the only way. Here I’ll show you the complete solution to fix this issue.
Windows 10 Disk Cleanup
There are many third party system optimization software that can help delete the junk files, but Windows 10 built-in Disk Cleanup is enough in most cases. From Windows XP to the latest Windows 10, I always use this utility to free up disk space. It is easy to use, runs fast, and is able to clean up most common types of unnecessary files. The most important aspect, it is safe.
Starting with version 1803, Windows 10 Disk Cleanup is incorporated into Windows 10’s Settings app, which has more options. In addition, you can set to free up disk space automatically. However, the traditional standalone Disk Cleanup utility is still available.
Steps to free up space with Windows 10 Disk Cleanup:
: Press and on keyboard, type cleanmgr, and then click OK.
: Select the drive that you want to cleanup.
: Click the check-box in front of the files that you want to delete and click OK. If you are not sure what the files include, click it and you’ll see the description.
: Confirm this operation by clicking Delete Files.
Disk cleanup will begin.
: Repeat the steps above to clean up system files.
If you never or have not free up disk space on Windows 10 for a long time, Disk Cleanup utility may help you regain several GBs of disk space. To get more free space in C drive, you may try the additional steps below.

Expand C drive larger
Disk Cleanup and the additional methods help you free up disk space on Windows 10 more or less, but you cannot fix the low disk space issue completely, especially when C drive is created small. Several GBs of free space will be eaten up quickly by new generated junk files. You’d better expand C drive as large as possible.
Download NIUBI Partition Editor Free edition and follow the steps in the video.

Running computer in right way
To completely fix C drive out of space issue, you may consider following options:
- If the entire disk is small, replace it with a larger one.
- Default installation path of all programs are in C drive, change the path to other separate drive (such as D) when installing programs.
- If you already installed the programs to C drive and do not want to reinstall, change the output path of the programs to other large partitions. The programs for videos, games and projects will generate many large files.
- Run Windows 10 Disk Cleanup as monthly maintenance utility.
