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 files, such as songs downloaded from online
stores, are encrypted to prevent the files from being unlawfully dis-
tributed or shared. Content providers use the DRM technology to
encrypt these files when applicable. During the encryption process,
the content provider creates a license which specifies how and when
the file can be used. Files that have licenses associated with them
are called protected files. More information about DRM (Forward-
Lock, Combined Delivery, Separate Delivery, etc.) was provided in
“How Album Handles DRM” in Chapter 3.
The previous figure of File Manager’s List View showed non-DRM
files. The figure below is a sample listing of DRM files. Similar to
the Album application explained in Chapter 3, “key” icons are used
to denote DRM files.
DRM files that can be used are identified by a key icon (with no line).
DRM files 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.
