KAP Full vs. Standard Version

What’s the difference between the full and standard zip versions for Windows?

The standard version contains a basic set of most commonly used extension. The “full” build contains all extensions provided by KNIME.
While the latter is convenient to use it also slows down the installation due to the number of extensions. And you hardly every need all of them, therefore I personally prefer to only install the extension into the standard version that one needs.
