I wish I wouldn't always give stories I write bland titles like "Encaged" or "Free"... it's hardly ever possible to find what I'm looking for without having to open dozens of files. :/
I find it easiest to organisw it into folders - a folder for writing, a folder each within that for multi-chaptered stories and another for all of my short stories.
