After looking at my storage use in Windows 10, I noticed that a lot of storage is taken up by temporary files.

According to Settings, about 54.4GB is being used. However, Disk Cleanup only shows 3GB – which is Windows Update Cleanup files I can't delete.

Settings > System > Storage and click a drive.

I can't find a solution searching for it. One potential solution was to check the C:\Windows\Logs folder for huge logs, but the folder is only 28.8MB. Another one was to run Disk Cleanup, but it didn't work (as shown above).

I ran WinDirStat, which shows 75% if the disk being used by the Users folder. Here's a screenshot.

Here are the main (>1GB) folders that are using a lot of space in my Users folder.

What are these temporary files? And how can I delete them?

I have a Dell Inspiron 3541 with Windows 10 v1803.

Close most of the open programs. Hit windows key. type %temp% and delete everything in there. There will be files it says it can't delete. You can just skip those ones. The rest of it is usually able to be deleted.
