Today we are going to talk about Windows Libraries and exactly what they are. If you are using a Windows 7 computer in all likelihood you have seen a category in your Windows Explorer called Libraries. Most people who look at it simply think that they are their main folders just like in Windows XP. I think Microsoft made these just to be confusing. The far truth is that they are not folders at all. A Library is actually a compilation of folders that are located on your computer. It is a collected view of several folders all put together. The Library allows you to organize your folders by date, type or last modified.
