How do YOU organize your computer files?

Hello fellow monkeys,

I will be entering my junior year, and I already have many files pertaining to internships. I was wondering if you all had any tips on how to keep your computer files named and organized. Each cover letter that I have is a different variation for my name because I was worried to name my file something along the lines of "Citi Cover Letter." This is consistent for a lot of my files.

I want to become more organized junior year, so I will be prepared for first round interviews. How do you organize the files on your computers?

Thanks!
