shellcode: file manipulation

[hippofear () gmail com]

Does anybody know of any good resources or examples of working with files through shellcode (windows)?  I find a lot of 
information on shells but none on using the file system.  I'm trying to move the all the files in the Desktop folder so 
that most icons will be removed from the desktop. 

I know i have to find all the files in the desktop folder, then loop through and move them 1 by 1.  So far i have found 
MoveFileEx to use but thats all.
