code for walking a directory tree, not sure doing right

[EDN Admin]

I am not sure I am detecting files and directories correctly. I want to detect files (but not sparse files), and directories, even hidden ones. I am trying to get a system file and dir count. any help appreciated. I think I have this correct,
but no matter what I try, it crashes at level 16 (it goes as deep as level 18 or 19).
older attempts I have made at walking a dir tree where I have immediately recursed on finding a directory have failed miserably due to the way XP works.
