You can figure out the directory structure AND create/delete files and directories by using a series of xp_cmdshell commands in Query Analyzer, as long as you have admin priviliges in SQL Server. Then use good old DOS commands.
master..xp_cmdshell 'dir c:\' --see files and directories
master..xp_cmdshell 'md c:\myDirectory' --create 'mydirectory'
master..xp_cmdshell 'rd c:\myDirectory' --delete 'mydirectory'
You get the idea.
