That is an excellent point that I think deserves expanding.
I submit that files and directories ARE difficult concepts. Pretty much everything is difficult when you look into it enough.
I remember of the time they pointed the Hubble Telescope into a seemingly empty patch in the sky and with long exposure or something, we saw tens of thousands of galaxies from billions of years ago.

Back to the subject at hand, I tried installing gentoo one time and it prompted me for something. I only vaguely remember the word "inode". Here is the first paragraph from the wikipedia from the article on inode:
The inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block locations of the object's data.[1] File-system object attributes may include metadata (times of last change,[2] access, modification), as well as owner and permission data.[3] Directories are lists of names assigned to inodes. A directory contains an entry for itself, its parent, and each of its children.

Files and directories may be an easy concept to understand if you have been exposed to them long enough (not sure how long is long enough) BECAUSE we have a good abstraction. I never had to learn what inodes are or how a filesystem works to use a computer. Can we accomplish something similar with version control?
