I have come to a problem... i have a pictures folder which has lots of subdirs and 
lots of irregular filenames such as "kdjfksjdf.jpg", "kdjflkajsdfasd.jpg" 
usually i renamed them randomly to avoid the same filenames when i grabbed it from internet...
So i want to upload them to the website and i want them arranged in good order....

Each folder should be ordered by numbers 1, 2, 3.....
Each folder has at most 39 files, 1.jpg, 2.jpg, .... 39.jpg
How can I do this?

So .... Super XP has provided batch file....

I 've done a little programming, it is fun! 

*******  save the following as .BAT file and modify vars as needed **********

        @echo off
        
        set cc=0
        set dd=1
        set od=D:\1
        set td=D:\2
        set nn=39
        set ex=jpg
        
        cls
        echo.
        echo 			Windows XP Batch file
        echo 			Created by Zhihua Lai, 2007-Aug-30
        echo 			The program can move all the %ex% files in %od% folder into
        echo 			%td% folder and rename it by number
        echo 			each folder (also labeled as number %dd% var) contains at most
        echo 			%nn% pictures....
        echo.
        
        echo Press any key to continue, press Ctrl-C to exit....
        pause >nul
        
        rem cls
        
        if not exist %td% mkdir %td% && echo %td% created...
        
        for /f "usebackq delims==" %%i in (`dir /s /b %od%\*.%ex%`) do (
        	call :dothing "%%i"
        ) 
        
        goto :clear
        
        :dothing
        	if exist "%1\nul" goto :end
        	if not exist "%td%\%dd%" mkdir "%td%\%dd%" && echo "%td%\%dd%" created...
        	set /a cc=cc+1 >nul
        	move %1 "%td%\%dd%\%cc%.jpg"
        	echo %1 has been moved to "%td%\%dd%\%cc%.jpg"!!!!
        	if /i "%cc%" EQU "%nn%" set /a cc=0 && set /a dd=dd+1
        goto :end
        
        :clear
        	set cc=
        	set dd=
        	set od=
        	set td=
        	set nn=
        	set ex=
        
        :end
