* With System Center Configuration Manager 2012, a new concept called the content library was introduced.
* The content library stores everything related to Configuration Manager efficiently on the disk (distribution point).
* Whenever the same file appears in two different packages, the content library only stores one copy of that file. There are, however, references indicating the file belongs to both packages.
* The content library is referred to as the "single-instance store" since it contains only one instance of any file.
* By introducing the content library, we are maximizing storage space and avoiding the distribution of files that are already distributed on the distribution point, so we conserve bandwidth on the WAN.
