Libraries Are New in Windows 7.

Libraries are new in Windows 7. Here are answers to some common questions about libraries.

What is a library?
Libraries are where you go to manage your documents, music, pictures, and other files. You can browse your files the same way you would in a folder, or you can view your files arranged by properties like date, type, and author.

In some ways, a library is similar to a folder. For example, when you open a library, you’ll see one or more files. However, unlike a folder, a library gathers files that are stored in several locations. This is a subtle, but important, difference. Libraries don’t actually store your items. They monitor folders that contain your items, and let you access and arrange the items in different ways. For instance, if you have music files in folders on your hard disk and on an external drive, you can access all of your music files at once using the Music library.

How do I create or change a library?
Windows has four default libraries: Documents, Music, Pictures, and Videos. You can also create new libraries.

Here are some ways you can modify an existing library:

Include or remove a folder. Libraries gather content from included folders, or library locations. You can include up to 50 folders in one library. For more information, see Include folders in a library.

Change the default save location. The default save location determines where an item is stored when it’s copied, moved, or saved to the library.

Change the type of file a library is optimized for. Each library can be optimized for a certain file type (such as music or pictures). Optimizing a library for a certain file type changes the available options for arranging your files.
