Seventy items isn't bad. Should take you an afternoon to manually move them all. Um...when you say "70 runtimes," I assume you mean that most of the items unzipped or otherwise unarchived as a file directory ending in "Runtime," right? And on a Mac, that would be "Runtime_1," "Runtime_2," "Runtime_3," right? Well, if you still have access to Classic mode (boo, Intel chips!) Martin C's "MacInstaller" -- freeware available at http://www.soft-rabbit.com/ -- will automate it for you. With MacInstaller you can drag and drop the entire directory, and install it into the new directory of your choice.
