Hi Marcin,

Installing a package /usually/ refers to installing a package through
the Emacs built in package manager.
http://www.emacswiki.org/emacs/InstallingPackages

These packages get installed in the 'package-user-dir', you yourself
should not have to manually modify any contents in that directory.
If you want to try and clean up your package management I suggest
taking a look at
use-package https://github.com/jwiegley/use-package
and Melpa https://github.com/milkypostman/melpa

Installing a package manually would mean adding the path to your package
to our load-path, and then require it manually. Though looking into
Emacs' built-in package manager is worth the effort.

So instead of removing them from your package-user-dir manually, try adding the
packages you need through use-package and let your Emacs configurations
handle it for you.
