The easiest solution is to copy and the paste the project :) easy isn't ?
What i think is probably the better solution:
Put your php.exe and zf.bat in your path (SYSTEM PATH) so you can execute its command from anywhere you like:
Go to system properties -> advanced tab -> environment variables button ->
then choose the "path" form system variables and add the path to your PHP.exe and ZF.bat
Looks something like this
D:\wamp\bin\php\php5.2.6;D:\Workspace\Zend\ZF\bin;D:\Workspace\Zend\PHPUnit
DONT forget to add the ";" between every executable ! .
once you did this .. and form your webroot dir you can execute any ZF Tool Command you like
