|[+] Describe :
|[+]
|[+] At the first search dork and choose a target
|[+]
|[+] Like this : http://www.spacetechgroup.in
|[+]
|[+] Add this to the end of target URL: downloadcode.php?d=
|[+]
|[+] After [?d=] you should enter your file name that you want to download!
|[+]
|[+] Fore example download in that target index.php:

|[+]
|[+] In some targets you can only download files that they're in
[Current] directory!
|[+]
