After installation, you forgot to delete the setup or downloaded file.

Now, both the setup file and the installed files are taking two different spaces (5gb + 5gb = 10gb).

This is something almost everyone does and I can assure you it’s nothing to be ashamed off.

If you have enough storage to keep both the setup and installed file, that is fine. But, if you don’t have enough storage on your computer, you have every reason to consider deleting the setup file after installing.
