The importance of keeping things neatly placed and labeled should never be considered overrated. When it comes down to animation if you do not have everything placed right especially when working with a group of people on a project things can get really gruesome. Every time you create a new texture or save a new model you should always make sure to place things in folders that are easy interchangeable and named for easy understanding of what it is there for. Also deleting any unwanted or unused materials, models, or files of any kind within those folders can make things much easier as well. When things like this get over looked that is when you start to find that you will have problems transferring files or even working withing your own computer because of the clutter and missing file locations that can occure from this causing you a huge headace.
