Extension that adds additional capabilities to an Adobe software program; can be installed and removed using Adobe Extension Manager; saved in a zipped format that is decompressed when the extension is installed. Adobe extensions are similar to plug-ins since they expand the functionality of a program. For example, the Dreamweaver HTML5 Pack provides additional support for HTML5 and CSS3 standards within Dreamweaver CS5. NOTE: The ZXP format is only supported by Adobe Extension Manager CS5 and later. Previous versions use the .MXP format, which was originally developed by Macromedia.
The zxp file extension is associated with ZX-Painbrush. The ZXP file format is text-based and contains a bit-pattern as well as the ZX-Spectrum color attributes in hexadecimal.
