Windows 7 provides users with several libraries that consolidate different types of files, such as music or video, into one easily accessible location. But what if you want to add your own folders to these libraries or remove them? Follow these four steps to find out how!
Step 1: Launch Computer from the Start menu.
Step 2: In the pane to the left, expand the Libraries folder by clicking the small triangle next to it if the list is not already visible.
Step 3: Right-click on the Library you want to modify and select "Properties" from the menu that appears.
From this new window you can add or remove the included folders in the Library.
Step 4: To remove an entry simply select it and click "Remove."
Step 5: To add a new folder to the Library, select "Include a folder…" and navigate to the folder you wish to add. Select the folder and click "Include Folder" and the folder’s contents will be included in the library.
