How File Manager handles DRM
DRM is Digital Rights Management, a method of controlling the us-
age of protected media objects after they have been downloaded.
Some digital media les, such as songs downloaded from online
stores, are encrypted to prevent the les from being unlawfully dis-
tributed or shared. Content providers use the DRM technology to
encrypt these les when applicable. During the encryption process,
the content provider creates a license which species how and when
the le can be used. Files that have licenses associated with them
are called protected les. More information about DRM (Forward-
Lock, Combined Delivery, Separate Delivery, etc.) was provided in
How Album Handles DRM” in Chapter 3.
The previous gure of File Manager’s List View showed non-DRM
les. The gure below is a sample listing of DRM les. Similar to
the Album application explained in Chapter 3, “key” icons are used
to denote DRM les.
DRM les that can be used are identied by a key icon (with no line).
DRM les that are invalid (cannot be viewed or played because
license has expired or been used) are indicated by a key icon with
a diagonal line running through it.
