/** 

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.
