Batch file-Change the target directory to wherever the file is?

I need to make a batch file change the directory to wherever it is currently stored. I know how to use the "cd" command, but I don't know how to get the current directory of the file. Can someone please help?

) else (
@echo installing the 32bit version of divice Driver

Actually I asked a friend about half an hour ago. He showed me a much simpler way: %cd% returns the current working directory. So I solved the problem with "cd %cd%" for anyone else having the same problem.
.  if %cd% does what you want, that's great, but it is not equivalent to %~dp0.
.  %cd% = drive and path of current directory (may change).
.  %~dp0 = drive and path where batch file is located (can't change).
Thank you for sharing the information (although I don't really see how that's much simpler than "%~dp0")!

Easier to remember :)
Ah, of course, of course...
Try google searches using the additional keywords of "relative links".
Are you sure? The dot (.) directory is relative to the user's session, not relative to the saved location of the script (what DOS-kiddies call a "batch file").
Yes. I'm trying not to spoon-feed, but %~dp0 points to the script's current path - which information may be found in the very first hit of a Google search for "batch relative link". :)
Cool. Thanks for giving me some new information. From looking at a couple of those links, I've got to say: modern "Windoze" batch program looks even more obfuscated than Perl!
