What is a ZXP file?
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.
