When students first start learning how to build websites they have no idea of the importance of naming stuff and knowing in 6 months where that stuff is and what that stuff means. File naming conventions are essential in getting good with organizing your stuff.
This is a great link telling you not only how to name a folder or file a certain way but also the rational behind why you should name it that way.
After reading it I learned that using underscores in file names and folder names is bad. I will only use dashes from now on.
The underscores are hard to see if the file or folder is a link. That’s something I didn’t even think about.
