If I understand it correctly, git DOES track folders/directories. In
most operating systems, directories are really just special files
containing pointers to and meta-information about other files. Git can
be understood as a special kind of file system which keeps the history
of it's contents, and not just the current contents.
Git uses three type of objects, blobs, trees, and commits all of which
are identified by the SHA1 hash of their contents, which are used as a
kind of pointer value.
Blobs represent the leaf files, at some point in time.
Trees represent a directory at some point in time, they contain a list
of the SHA1 pointer to each blob or tree (subdirectory) in the
directory, along with its file name, and mode.
Commits point to a particular tree, and to 0 or more parent commits.
What git doesn't do is track files OR directories directly by name.
