Thanks for the reply, guys!

foxyloxley, sorry if my question seemed incomplete or vague as to why I asked for the maximum depth of NTFS's sub-directory is that its a question presented to the network security course that I'm currently taking for us, participants.

Just as The Grunt mentioned "why hell it matters?" well it didn't mattered much to me as well until I got into this network security course. I've searched in google and several other search engines namely hobot, web crawler and yahoo but only came up with results discussing the maximum path length instead of the subdirectory depth.

Tim_Axe thanks for the reply as well as the link to Microsoft's knowledgebase.
