Use the DOS "find first" and "find next" calls, numbers 4E and 4F.  They do
filename pattern matching and if your pattern is, say, \foo\*.* you get all
of the files in directory foo.  It returns the time, date, and size of the
file along with the name so you get pretty much everything you'd get from
reading the directory yourself, but is much, much, easier.
