Say Johnny makes an EMPTY file. It is called `foobar.py`. When Johnny allows it to be executed, he runs `chmod 755 foobar.py`. The file now has the metadata of

```
-rw-r--r-- 1 johnny staff    0 Dec 27 22:53 foobar.py

```

Where is all that metadata stored in that file? The size of the file is 0, so how does it keep the metadata when it is transferred to another drive?
