My laptop says the disk is full, so I'm trying to make some space by removing some files. But the ls output doesn't make sense for me. The Downloads directory, in reality, is empty... I guess the issue is elsewhere, but I have no idea of how to start solving the problem.

The problem persists after the new system installation.

ls -lSh output:

maria@maria-Vostro-3360:/media/maria/2845d360-0b89-46c8-97ff-dc5e9862949e          /home/maria$ ls -lSh

In Linux filesystems the directories are inodes like regular files, but they contain references to other files (file names, in particular). So their disk size is roughly proportional to the number of entries they point to (child files/directories). However when you erase child files and directories the space is not always reclaimed, so your output above is just showing you how big your Downloads directory inode had to grow once to contain the data for a few hundred files.
