Ok so I want to re-install snow leopard on my imac early 2007 I have the Sl disks but I don't have my copy of iwork 09 and ilife 11. I installed it on my imac before I sold the disks. now I want to know how I can take my apps that I want to save to a flash drive. So could I just copy the application directly to the 4gb flash drive or do I have to copy some file along with the app?
