Bridge : FileIO Class
Tests whether a file or directory exists on the SD card.
This communicates with the Linux distribution through Bridge. While functionally similar to the SD library, the underlying code and hardware connections are different.
filename: the name of the file to test for existence, which can include directories (delimited by forward-slashes, /)
boolean : true if the file or directory exists, false if not
