List all folders, and subfolders, in a directory

Question

I'm trying to find a way to list all folders, and subfolders, in a directory.  I ran the code below and got a message that says 'Access is Denied'.  There is no way access is denied to that folder. How can I list all folders, and subfolders, in
a directory?
--'C:\Users\Ryan\Desktop\Coding\';
set nocount on
declare @curdir nvarchar(400)
declare @line varchar(400)
declare @command varchar(400)
declare @counter int
If (select count (*) from sys.objects where name='Output') <> 0 DROP TABLE output
If (select count (*) from tempdb.sys.objects where name like '%#Tempoutput%') <> 0 DROP TABLE #Tempoutput  
If (select count (*) from tempdb.sys.objects where name like '%#dirs%') <> 0 DROP TABLE #dirs  
create table #dirs (DIRID int identity(1,1), directory varchar(400))
  Set @command = 'dir "C:\Users\Ryan\Desktop\Coding\Microsoft Access\" /S/O/B/A:D'
 insert into #dirs exec xp_cmdshell @command
  set @counter = (select count(*) from #dirs)
create table #tempoutput (line varchar(400))
create table output (Directory varchar(400), FileSize varchar(400))
    While @Counter <> 0
      Begin
        Declare @filesize int
        set @curdir = (select directory from #dirs where DIRID = @counter)
        set @command = 'dir "' + @curdir +'"'
        insert into #tempoutput
        exec master.dbo.xp_cmdshell @command
           select @line = ltrim(replace(substring(line, charindex(')', line)+1,len(line)), ',', ''))
           from #tempoutput where line like '%File(s)%bytes'
           Set @filesize  = Replace(@line, ' bytes', '')
        Insert into output (directory, Filesize) values (@curdir, @filesize)
        Set @counter = @counter -1
       End
       Delete from output where Directory is null
select * from output
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Can you tell us how you're executing this code? Is it called from sql agent job or are you executing it by calling code directly?
Did you try creating a proxy for xp_cmdshell and then executing it?
