# View or Extract PDF Portfolio Documents

A PDF Portfolio is a PDF file that contains multiple documents and an Adobe Flash interface that can provide information about them and allows you to navigate to them. The subfiles are not necessarily in PDF format; the portfolio might contain a PowerPoint presentation or a word processor file.

By default, the KeyView Viewing SDK opens PDF Portfolio files using the Adobe Acrobat ActiveX control. This requires that your users have Adobe Reader and Adobe Flash installed. Alternatively, you can configure KeyView to use the archive format viewing engine. This allows you to open the sub-files of the portfolio PDF without needing to have Adobe Acrobat or Adobe Flash installed, but does not allow you to view the Flash interface.

To choose how to view PDF Portfolio files

1. Open the `kvsdk.ini` file with a text editor. The file is installed in the root of the Windows directory.

2. In the `[VAPI]` section, change the value for the file category `1048`:

   - To use the Adobe ActiveX control:

         1048=doc 0 kvaxcc.dll

   - To use the archive format viewing engine:

         1048=zip 0 kvarcve.dll

3. Save and close the file.
