where do i extract the files after im done downloading the themes?

If it's a new theme with a .xtreme extension, all you have to do is double click the theme. For older .zip theme packs:

Q) How do I install and preview downloaded themes?

A) Open the Themes tab in NextSTART or WorkShelf preferences. If you have downloaded the theme zip files to the \Winstep\AutoInstall folder, all you have to do is click on the Import button (the one with the box icon with arrows pointing out) and NextSTART/WorkShelf will automatically install all of them. If not, you will first have to provide the path to where the theme zip files were downloaded. Once the themes have been installed, they will be available from the list of available themes. Select the theme you want to preview and click on the Diskette button or click on the Preview button below. Once you are happy with the theme you selected, press the OK button in Preferences to make it effective.

Hope this helps,
