When you first open Volocity you will be prompted to either open an existing Library or create a new Library. Libraries are databases where your images are stored and they must be created if you want to do anything in Volocity. You can create a new library for each experiment or have a number of experiments in a single library. I would probably recommend the former approach in most cases since if a large library with a lot of data in it is corrupted then all that data will be lost.
