You’re not alone! I had developed a habit of cleaning downloads and files since storage was somewhat scarce when I started using PCs in the 90s. Now it’s so cheap that I will simply delete very large files, then name the folder yyyy-mm-dump and place it with others in a backup folder somewhere. If I ever have to recove disk space I will glance over and delete it then, but more often it has been more valuable to dig up some meme or image.
