This question already has an answer here:
I've created a bat file php "d:\Dropbox\sync.php" Then I put this file into system32 folder to be able to call it anywhere in my system. sync.php needs an argument.
When I enter some certain folder in explorer and type in cmd sync arg1 my script says it has no args, but it works if I do in the common way: call it directly without bat.
</div>
You need to use %1 in the sync.bat file.
Just like this:
php "d:\Dropbox\sync.php" %1
