The first time you launch the Extension Manager, it searches for previously installed extensions and displays them. You can enable any extension by clicking the On/Off checkbox.
You can also launch the Extension Manager from the Start menu in Windows or the Applications folder on the Macintosh.
For example, to sort alphabetically by author name, click the Author column. To reverse the order of the sort, click the column heading again.
A check mark in the On/Off column next to the extension indicates that it is enabled; if there is no check mark in the column, the extension is disabled.
If you have installed large numbers of extensions using the Extension Manager, you can selectively enable and disable them to help manage the application’s performance.
The extension is removed.
You can get more information about an extension, rate an extension you’ve used, or find more extensions on the Adobe Exchange.
The Exchange Manager starts your browser and loads the Adobe Exchange website, where you can find information about any posted extension, rate extensions you’ve used, and search for and download a wide variety of extensions.
