If you haven't already started, you might want to backup your stuff. You can rest assured that PBooost doesn't like to delete anything. For example, PBooost will not delete a folder that has content. You can't delete individual items or groups of items. You can delete an empty folder. Sometimes a folder might look empty, but still have something in it. The unseen items may be geometry files, textures, etc. PBoost will give you a warning about that. I usually leave those folders alone and look at them more closely with a file manager program. You might want to sketch out a plan before you actually get started. Here is an idea of banks you may want to create: 1.) Mike 2.) Vicky 3.) P4 characters (Dork, Posette, etc) 4.) Projects 5.) Stephanie You get the idea. Just think of groups or banks of things you will use. Then create those banks and move your stuff to them.
