File system
To better understand the forensic process of an iPhone, it is good to know about the file
system that is used. The file system used in the iPhone and other Apple iOS devices is
HFSX
, a variation of
HFS Plus
with one major difference. HFSX is case sensitive whereas
HFS Plus is case insensitive. Other differences will be discussed later in this chapter. OS X
uses HFS Plus by default and iOS uses HFSX.
