Using a Memory Card
File Name Rules
When naming files stored on the memory card, the
following rules apply:
• The file name can contain both ASCII and
Unicode characters.
• File names up to 32 characters long, including
the file extension and folder name, can be
displayed by your phone. File names up to 255
characters long, including the file extension and
folder name, can be read by your phone. If a file
name is more than 32 characters long, but no
more than 255 characters long, your phone
displays an abbreviated name for the file, but
does not change the name of the file on the
memory card.
Note: Only files with names no longer than 32
characters can be stored in your phone's
memory. When you copy or move a file
with a longer name to your phone's
memory, you are prompted to rename the
file.
• The file name must be in a language your phone
can display. To see which languages your
phone can display, select Settings >
Display/Info > Language. Your phone can
display the languages listed and other
languages that use the same alphabets.
