+(Optional) These instructions require uncompressing the data. In principle it is possible to install the data directly from the compressed files. First you must install a command line tool which can unzip data and add it to your environment path in command prompt (good examples include 7zip or GnuWin32 gzip). After that you'll need to create a .bat script to use the command line tool, e.g.:

 (Optional) You may want to change where MonetDB stores the data, which is accomplished by modifying the .bat files directly. Open up WordPad by right clicking and selecting "Run as Administrator" (needed in order to edit the .bat file). Open up M5server.bat, and add the following after `:skipuservar`:
