: If you have stored too many files in memory, the
operation speed of the system slows down. Using an
optional memory card helps you clear up this problem
and lets you enjoy more music files.
About DRM, licenses, and protected files
Some digital media files, such as songs downloaded from
online stores, are encrypted to prevent the files from being
unlawfully distributed or shared. Content providers use a
technology called Digital Rights Management (DRM), to
encrypt the files. During the encryption process, the
content provider creates a license which specifies how and
when the file can be used.
For example, a content provider could create a license that
allows you to play a certain file on your computer, but not
on your phone. Or, a license that allows you to play a
certain file on your phone, but only for a month, or perhaps
only a certain number of times. Files that have licenses
associated with them are called protected files.
If you want to copy a protected file from your desktop
computer to your phone, use the desktop Media Player to
synchronise the file to your phone. This will ensure that the
license is copied along with the protected file. In the
desktop version of Windows Media Player 10 or later, you
can use the
Sync
feature to automatically copy your audio
files, video files, and play lists to your phone every time
you connect.
