I unzipped the plugin files into a subfolder in APO 2.06c.  

How do I open them when working on a fractal in APO?

When I click the "open file"  I find the plugin folder and it is empty, sinde the drop down menu in the window that opened only has 3 selections to choose from.  .flame.flm3 , .fla.apo, and ifs

Please advise how to use these.

When I unzipped the file into the plugin folder, they all unzipped.  I just can't find them when in APO.

Thanks, Joy
