Building a tree from individual file paths in T-SQL

Usually I'm the one answering database questions, but I'm completely stumped here. Looking for some T-SQL code to get the results I need.

I have a table that contains a couple of file paths, lets say the table is called FOLDERS and the field name is FOLDER. Some results would be:

C:\inetpub\custerr\en-US\
C:\inetpub\history\CFGHISTORY_0000000001\
C:\RIPPED\
C:\Users\Owner\Desktop\
C:\Users\Owner\Documents\Bar128\
C:\Users\Owner\Documents\BlackBerry\Backup\

etc.

Basically what I need to do is figure out how to select these in such a way that I can build a collapsible folder tree in an application. So my results would need to be something like:

c:\
c:\inetpub
c:\inetpub\custerr
c:\inetpub\custerr\en-US\
c:\inetpub\history\
C:\inetpub\history\CFGHISTORY_0000000001\
C:\RIPPED
C:\Users
C:\Users\Owner
C:\Users\Owner\Desktop
C:\Users\Owner\Documents
C:\Users\Owner\Documents\Bar128
C:\Users\Owner\Documents\BlackBerry
C:\Users\Owner\Documents\BlackBerry\Backup

Anyone have any ideas? I know I could do this using a temp table and a cursor, but I'm wondering if there is a more efficient way first.
