Reminds me of this one-time a girl at school had copied a shortcut to a DOC file onto the floppy-disk and submitted it at school.

The teacher had a hard time explaining shortcuts to her. The girl kept insisting that the PC at school was broken as the shortcut worked in her machine at home.

What I hope really happened is that the savvy student bought herself an extra day to complete the assignment!

A friend of mine "copied" a bunch of songs from an audio CD to a floppy disk this way.

A guy I knew used to reencode his songs as 16 kbps mp3 files to save space. When I told him they sounded horrible, he told me "no problem, I can always reencode them back to 128 kbps!"

I wonder how much disk space a file system link would take.

Typically the filesystem "page" or "inode" size. Usually 4KB.

Page/block size is not inode size. While filesystems very often work in chunks of 4KB, the normal inode size is 256 bytes on ext filesystems and 1KB on NTFS. They get packed together.

Wait. That's illegal!
