Computer Hope

Can anyone help me with a batch file to compress multiple depth subdirectories?

I would like to be able to turn

+---Pix
|   |   a.jpg
|   |   b.jpg
|   |   c.jpg
|   |   
|   \---Docs
|       |   a.doc
|       |   b.doc
|       |   c.doc
|       |   
|       \---Bills
|               a.xls
|               b.xls
|               c.xls
|               
\---Wishlist
    |   x.jpg
    |   y.jpg
    |   z.jpg
    |   
    \---Adverts
        |   x.doc
        |   y.doc
        |   z.doc
        |   
        \---Income
                x.xls
                y.xls
                z.xls

into

+---Pix
|   |   Pix.7z
|   |   
|   \---Docs
|       |   Docs.7z
|       |   
|       \---Bills
|               Bills.7z
|               
\---Wishlist
    |   Wishlist.7z
    |   
    \---Adverts
        |   Adverts.7z
        |   
        \---Income
                Income.7z


Notes:

• My archiver (7z.exe) is already set in my path environment variable, so the batch file doesn't need to know where it is.
• The contents of Piz.7z (for example)should only include the files in the Pix folder, not the contents of Docs or Bills.

Any help would be greatly appreciated. 

If you are using 7 Zip "-r-" can be used to copy only current directory without subdirectories

Hi 
May be like this way :
@echo off
Title 7z Compressing muti-subfolders
:: set the current directory to the batch file location
cd /d %~dp0
Call :Check_7Zip
@for /d /r %%D in (*) do (
PUSHD %%D
@for %%A in (*.*) do (
echo "%Zip%" a "%%D.7z" "%%A"
"%Zip%" a "%%D.7z" "%%A"
)
POPD
)
pause
Exit
::-----------------------------------------------------------------------------------------------------------------------------
:Check_7Zip
Reg Query "HKEY_CURRENT_USER\SOFTWARE\7-Zip" /v "Path">nul 2>&1
If [%errorlevel%] EQU [1] ( echo 7-Zip is not found !
) else (
@FOR /f "tokens=2*" %%i in ('Reg Query "HKEY_CURRENT_USER\SOFTWARE\7-Zip" /v "Path" 2^>nul') do (Set "Zip=%%j7z.exe")
)
Exit /B
