Well ladies and gentlemen, thank you for all the info you kindly sent, I had a look at PBoost and decided it was worth having, I like the idea of being able to keep track of things. However, back to the runtime folder, if I have more than one runtime will they have to be renamed, eg, runtime1, runtime2. 

Sorry to keep going on about it, but I really want to get all my files as organised as I can get them so I don`t slow my system down too much.  :biggrin:

Paula.
