Around 20MB of free disk space are required for installing the distribution for a single platform.
In order to extract the distribution on Linux an extraction tool for .tgz (TAR-GZIP) archives or for .zip (ZIP) archives is required. This can be the standard system tools tar(1) and gunzip(1) and or unzip(1).
On Windows you need the ability to extract .zip (ZIP) archives, this is normally included by default and the archive can be opened in the explorer using a double-click.
