Batch traverse subolders and rename files -

-

i traverse folder , it's subfolders, keep counter variable of current file , rename $counter$existingfilename.
e.g. 

$count = 1;   foreach $file in $folder   {     $file.name = $count + $file.name;     $count++;   }

the person can answer hero! :)
btw using windows 7.

all right, while pondering on questions in comment post (or maybe still making way site read them), here's trial shot:

@echo off set "rootdir=%~1" if "%rootdir%"=="" set rootdir=. set cnt=0 /r "%rootdir%" %%f in (*) (   set /a cnt+=1   setlocal enabledelayedexpansion   rename "%%f" "!cnt!%%~nxf"   endlocal )

this rename files prepending names numbers, this:

1file.txt 2program.exe ...

if like, can have way:

00001file.txt 00002program.exe

for you'll need make 2 changes above script (highlighted in bold):

@echo off set "rootdir=%~1" if "%rootdir%"=="" set rootdir=. set cnt=10000 /r "%rootdir%" %%f in (*) (   set /a cnt+=1   setlocal enabledelayedexpansion   rename "%%f" "!cnt:~1!%%~nxf"   endlocal )

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
