Mac: If you make a lot of folders for your projects, you know it can be a pain to get things organised. Post Haste is a free Mac app that allows you to create project-based templates so you can get started immediately.
Post Haste is very simple, but if you work on a lot of projects with the same workflow, it's a time-saver. Basically, Post Haste allows you to set up a folder and then all of the subfolders for a project in a click. So, if you're working on music and always have samples stores in one subfolder and instruments in another, Post Haste lets you create all that right away with a template.
