Yes. There is a host app that runs on Windows (TI Connect), Mac (TI Connect) or Linux (TiLP2). It gives you a view of the contents of the calculator's memory that looks like a file system. You can drag-and-drop any app or variable from the calculator to the host. You can drag-and-drop those files from the host back to the calculator.

You can also connect 2 TI calculators together through a 2.5 mm cable, and transfer files between them. I've actually never done it myself, but apparently it's possible.
