Memory Card
Folder Structure
The first time you insert the memory card into your
phone, three folders are created: Audio, Images,
and Video. In order to access files stored on the
memory card, you must store the given file in its
corresponding format folder: audio files to the
Audio folder, pictures to the Images folder, and
videos to the Video folder.
Because your phone creates these folders the first
time the memory card is inserted, you should insert
the memory card into your phone at least once
before using it with your computer.
Filename Rules
When naming files stored on the memory card, the
following rules apply:
• The filename can only contain ASCII characters.
• The filename can be up to 32 characters long,
including the file extension.
