/** 
Provides simple-to-use file system utilities.

The functions listed in "Copying, renaming, and deleting files" create and 
use a CFileMan object. They are useful for one-off calls, but for repeated 
use it is more efficient to use CFileMan directly.

Note that there is a very similiar group of functions available in EikFileUtils, 
which may be easier to use in GUI applications, as they do not require a file 
server session to be passed.
