I'm not clear as to your use of the word "Directory" in the examples above.
It appears that you mean context rather than directory. All the
documentation shows that loading a package is done by typing

<< name

where name stands for the name of the package you wish to load. See e.g. the
Help Browser on Working With Add-Ons|Loading Packages. E.g., if you want to
work with combinatorial functions you should type

<<DiscreteMath`CombinatorialFunctions`

Alternatively, you may type

Needs["DiscreteMath`CombinatorialFunctions`"]

or

Get[DiscreteMath`CombinatorialFunctions`]

(<< is an alias for Get). Perhaps all you need is to use ` (back quote) and
not ' (apostrophe).
