For flexible and convenient management of plugins, Foxit PDF Editor offers a Plug-in Management Platform, in which you can view the plug-in status, learn the information about the plugins installed, as well as manage the plug-ins as needed.
To open the Plug-in Management Platform, please choose Help > Plug-in Management.
Plug-in Status
Foxit PDF Editor lists the plug-ins that have been installed in the About Plug-in Management window. Some plug-ins will be loaded the first time you use the related features. When the plug-in is successfully loaded, a checkmark will be displayed in the Loaded column. You can view the plug-in status in the following two columns:
- Certified: Shows whether the signature of the plug-in is valid or not.
Loaded: Shows whether the plug-in has been loaded successfully or not.
Note: Some plug-ins are not loaded immediately (i.e. in the standby status with
shown in the Certified and Loaded columns). These plug-ins will be loaded and certified after you use the related features.
Plug-in Information
In addition to plug-in status, you can learn more information about the plug-in installed, including the name, date, description and legal copyright.
To learn the details of a plug-in, please click More… under the general description of the plug-in in the Plug-in Management Platform.
Plug-in Management
With the Plug-in Management Platform, you can manage the plug-ins as needed, including installing, enabling, disabling and uninstalling plug-ins.
Installing a Plug-in
Foxit PDF Editor allows you to install a plug-in in FZIP format. You can also install one or more plug-ins by using an XML file. An XML file defines the information about plug-ins to be installed, and should be used together with .fpi files. (Tip: For a plug-in in MSI format, double-click it to install it.)
- Select Help > Plug-in Management to open the Plug-in Management Platform.
- Click Install Plugin in the About Plug-in Management dialog box.
- In the Open dialog box, do one of the following:
- To install a plug-in in FZIP format, select FZIP Files (*.fzip) from the file type drop-down list beside the File name box, choose the file from your local disk, and click Open. When the installation completes, click OK.
To install one or more plug-ins by using an XML file, select Plug-in File (*.xml) from the file type drop-down list, choose the XML file from your local disk, and click Open. Then Foxit PDF Editor will verify whether the signature of the plug-in is valid or not. If it is valid, Foxit PDF Editor will load the plug-in. Otherwise, the installation will be terminated.
Tip: If you install plug-ins by using an XML file, please place the .xml file and .fpi files in the same folder to avoid an installation failure.
