Yes, it should.  DOS initializes the reserved fields of the ffblk on
calling findfirst(), so that it knows where to continue searching when
you do a findnext().  To make a list, you need something like the
following:

struct ffblk ffb ;
char file_list[20][14] ;
int fnd ;
int count = 0 ;

fnd = findfirst( "*.*", &ffb, 0 ) ;
while (fnd != -1 && count < 20)
   {
   strcpy(file_list[count++],ffb.ff_name) ;
   fnd = findnext(&ffb) ;
   }
