IF there are any components placed in a SKP model when Sketchup opens you can't purge them.
Unused components can be purged... and then they are only accessible from the Components folder again...
So, unless you want to somehow explode all component instances at startup and then purge unused [=ALL], you must always have some components in the browser of any previously-used SKP, where you have placed some components ???
