In Windows 7, you can mount folders in a library from several different locations, for example from your computer’s C drive, external hard drive, or network. The most important requirement for a new library location is that the content at that location be indexed or can be added to the Windows search index.
Folders that can be added to the Windows library
If the local location that is added to the library is not already an indexed location, it is added to the list of indexed locations.
It may take some time for this content to appear in the library after it is added, as it must be indexed before it appears.
1. if your folder is stored on drive C (system) ; yes – it can be added to a library !
2 If the folder is on an external hard drive/USB, it is available only as long as the drive is connected and the device appears in the navigation pane.
3. Folders cannot be added to removable media such as a CD or DVD.
4 If the folder is on a network, it can be added as long as the network address is indexed or available offline. If the network folder is not indexed, this is an easy way to make the folder available offline. You can then add it to a library.
5. if the folder is on another computer in your home group yes – it can be included in a library !
