I wasted 50% of my disk space because I didn't know the difference between Copy and Link. Deep dive into Inode, the secret of `rm` command, and why `pnpm` is faster than `npm`.

Filename is just a shell in Linux. The real identity is inode number. Secret of ls -i.

HDD is just a giant field of 0s and 1s. Magic that creates 'File' and 'Folder'.
