Windows theme used by Aston, a program that replaces the Windows desktop and shell with customized appearances; stores visual settings for the start menu, desktop, and panels; saved in a compressed .ZIP format.

The A2THEME compressed archive contains bitmap graphics as well as XML files that define the layout of the theme elements. NOTE: If you download an A2THEME file, you can double-click the file to install the theme, since Aston automatically registers the ".a2theme" file association when installed. However, because A2THEME files are saved in the ZIP format, the Web browser may automatically assign the ".zip" extension to the downloaded file. Therefore, you first need to change the extension to ".a2theme" and then double-click the file to install the theme.
