Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation.

Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
