Macromedia Extension Manager 1.x was a utility that was developed by Macromedia to manage extensions for its software applications.

Product history[]

Extension Manager 1.0 originally supported extensions for Macromedia Dreamweaver 3 that were downloaded through Macromedia Exchange, which was launched in April 2000.[1] Files to be installed were prepared as Macromedia Extension Installation (.mxi) files packaged into a Macromedia Extension Package (.mxp).[2]

Macromedia was acquired by Adobe Systems in December 2005.[3] The utility was renamed Adobe Extension Manager and its functionality was expanded to support Creative Suite applications. The .mxp package format was superseded by Adobe Zip Format Extension Package (.zxp) in CS5.5.[4]
