File Locations, can you explain

[HaraldHeim]

You should install Plugin Commander where you install your other applicatios. Usually that's C:\Program Files\. But if you can of course install it everywhere you like. Just make sure it has its own folder somewhere.

You don't need to install any plugins inside the Plugin Commander folder. Just leave the plugins where they are and select that folder in Plugin Commander.

You apply a plugin to an image in Plugin Commander and then copy and paste the image into PSP? If you know that you will use PSP on that image afterwards, you could also apply the plugin directly in PSP. I'm not quite sure if I understood you correctly.
