Select From The Same Table

My table is

CREATE TABLE [ARQ_Arquivos] (
[ARQ_ID] [int] IDENTITY (1, 1) NOT NULL ,
[ARQ_Descricao] [text] COLLATE Latin1_General_CI_AS NOT NULL ,
[ARQ_Link] [varchar] (255) COLLATE Latin1_General_CI_AS NOT NULL ,
[ARQ_DataHora] [datetime] NOT NULL ,
[ARQ_PastaID] [int] NULL ,
[ARQ_EPasta] [bit] NOT NULL ,
[ARQ_Criador] [int] NOT NULL ,
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

I need to make a folder tree in a sql query from that table where ARQ_ID is the father of
ARQ_PastaID and I need a result like

Folder1

Folder1/subfolder1

folder1/subfolder1/subfolder2

folder 2

folder 3

folder3/subfolder3

I tried with SELECT A.ARQ_Link, A.ARQ_PASTAID,
CASE WHEN A.ARQ_PASTAID IS NOT NULL THEN
(SELECT C.ARQ_Link FROM ARQ_Arquivos C WHERE C.ARQ_ID = A.ARQ_PASTAID)+'/'+A.ARQ_LINK
ELSE
A.ARQ_Link
END AS PASTA FROM ARQ_Arquivos A
INNER JOIN ARQ_Arquivos B
ON A.ARQ_ID = B.ARQ_PastaID and A.ARQ_EPasta = 1

but i repeat all files wrongly....and do for 1 level of subfolder only...how can I male it ??
