I have downloaded Gradle onto my computer, which runs on Windows 7. Now, I’m not sure how to unzip the files.
I can’t imagine what your problems. You just unzip the Gradle distribution zip to any folder on your system.
To have it run, you might set some environment things like adjusting the windows system path to include “%GRADLE_HOME%\bin” or to put Java on to the path. Nothing special.
And: don’t forget to have a look into the docs, online or with the distribution.
