Hi Again, > The *easy* way to do a deep copy is in fact to archive the root object and > unarchive the result.
Yes, I’ve come to that conclusion myself thinking about it. Apart anything else it offloads the problem nicely. In my case, I don’t need to archive it at all, I just need to load another copy of the same file……… The first load occurs at App startup and that can take as long as it needs, but I need the second load to be as fast as possible, this got me to thinking. At the moment my code does this: myNetwork = [NSKeyedUnarchiver unarchiveObjectWithFile:myFilePath]; Could I hold the data read here somewhere and use that to save re-reading the file the second time around?
