how do i clear out my local disk

[EXO-L]

so i went on my notebook after a long time and i turned it on to find a lot of useless apps on it  i deleted them all and even removed them from my recycling bin. the only thing i have saved on this notebook is songs that i have downloaded. there is nothing else in any of the other folders. but the thing is when i go to file explorer and go on to This PC, the local disk is always red and only ever has like 1-2 GB free of 21. i have nothing on this notebook. i have deleted and removed everything i don't need. FYI the bar was red before i even added the music. i have no idea what else to do so it would be great if someone could help me. Thank You

Also, the community Win10 Forums has the following suggestions:

In addition, I have found the utility Cleanmgr+ to have LOTS of options for removing Windows junk, including log files. I use it practically every day. You can get it from here: https://www.getclone.app/download/category/11-cleanmgr

Also, there is a freeware app known as Wise Disk Cleaner. I use it every day to get rid of junk files: https://www.wisecleaner.com/wise-disk-cleaner.html
