Okay its seems that there are a number of obj. files missing in my runtimes, along with who knows what else.

I created multiple runtimes using the tutorial for it I found on this site.  Not a problem for most of my stuff; however, it appears that some of my items are missing.  I noticed that these exist in the unzipped folders, but not in the runtimes.

I am assuming that when I copied the unzipped data to the runtime folders, windows Vista over-wrote the files rather than merging them. 

I take it that I probably just need to recopy the folders over, but they cause the same problem to remain.  Should I create new runtimes to keep the "offending" items in different folders or is there another approach.  

Also, with the folder names that are provided by some of the content creators, I have no idea whats in them ... Not a problem now as I don't have too much content, but I imagine it can be a problem when the amount of content on my harddrive exceeds my short-term memory.

Is there a way to rename folders?
