It's difficult to teach programming techniques through email.  There are
lots of approaches to solving this problem, but the basic methods
involve getting a local copy of the list of files by reading the file
directory one file at a time and then applying some sorting algorithm to
the list then displaying the sorted list.  A quick-and-dirty method is
to define an array of strings and fill it with the file names and then
to sort the array in some way - a bubble sort is easy to implement but
slow, quicksorts are faster.  This will use a lot of memory and your
array may not be big enough to hold all of the file names in the folder
you are looking at - leading to program crashes.  You could use a linked
list of files which can be expanded indefinitely in virtual memory but
is harder to sort -- the usual method of sorting a linked list is by
changing pointers to the next entry in the list.  Any basic book on
algorithms would probably discuss the basics needed to do something like
this.
