Relative folder paths

[Bill Vlahos]

Bob,

Thanks for the info. This sounds like a good solution if the problem  
is complicated.

Fortunately, in my case there are only  a couple of locations I need  
to find and they are all relative to the standalone. What I did was  
to simply put the defaultFolder into and invisible field on openStack  
so it would be saved somewhere. I then just keep changing the  
defaultFolder when needed because I know where the files are supposed  
to be.
