That way you won't forget there's a junction. So once you install a PSP version, move the plugins, etc., to the 'common' folder, and add a junction. In other words, if you replace your \Plugins folder with junction named Plugins that points to D:\Corel_Stuff\PSP\Plugins, PSP will think it is accessing \Plugins, not the junction target folder on a different drive. The difference is that a junction is transparent to programs. A junction is sort of like a Windows shortcut. You can instead use junctions to point to a 'common' folder such as my plugins folder. Then even if you delete the original PSP version, it will still work for the other version. But once the plugin is installed, you can simply copy it to any other version's plugins folder.
For instance, to install Perfectly Clear for X6 you need X6 installed. You need the specific PSP version installed to install that plugin (or the Creative Content extras). I have a separate folder (actually on a different drive) where I put all my plugins. Just to clarify a bit about plugins and multiple PSP versions.
