Treeview question

Hey All

I have the following in a database as records and want to recreate the paths in a treeview form.

The records are as such:

g:\
g:\data
g:data\projects
g:\data\projects\comp1\
g:\data\projects\comp1\data
g:\data\projects\comp1\data\word1.doc
g:\data\projects\comp1\data\word2.doc
g:\data\projects\comp1\data\word3.doc
g:\data\projects\comp1\data\word4.doc

How can i recreate the explorer paths in a treeview?
Any ideas?

cheers for any help
