Bruce:

Another way of looking at this is...
* PS7 came with its own set of native filters and plugins. As I understand it, somewhere between some and many of these are not compatible with CS.
* Into the PS7 plugins folder you installed additional 3rd party folders. This is a common practice.
* PS7 and CS have a preferences option to specify an auxillery plugins folder. * Forgetting the 3rd party plugins in the PS7 folder for a moment, if you point CS to the PS7 plugins folder via the preferences setting, CS will get real confused when it finds the incompatible PS7 filters and plugins, hence the Adobe warning you quoted.

Since you're going to have to go the hassle of moving/reinstalling plugins anyway, consider this alternative:
* Create a separate folder for your 3rd party plugins, e.g., \Common plugins * Install your plugins from scratch as Dave suggested into separate folders inside this new folder. Some plugins require serial number verification, even if you move them from one folder to another, so have the serial numbers handy.
* Update the CS preference to point to this folder
* Note: There are some 3rd party plugins that just don't work with CS and others that may need to be updated for CS compatibility. It will depend on your collection. If a given plugin works, it works. If not, you know the drill.

The benefits of this setup:
* You never have to move/reinstall plugins again, just update the preferences entry in the new PS version
* Having isolated 3rd party plugins like this makes it real easy to share them with other applications that can use PS compatible plugins.

Hope this helps connect a few more dots.
