ABSTRACT

Folders and les are set up in a hierarchical manner, which is to say that you “put” les or folders into other les or folders, and when you move the folder at the top, the rest goes along with it! In this way, you can organize where stu is and move it or copy it as a unit. Everyone who uses computers understands this system a little bit, or they wouldn’t understand how to use the computer (although I’ve had several friends who just dump everything on their desktop and clutter the hard drive randomly). is is the core concept of “inheritance,” which is what the folder analogy stands for. It simply means I can put an object or collection of objects into another object and move them all around from a single collection. Anything I do to the top-level folder gets applied to the rest of the folders and documents inside of it. For instance, if I “copy” a said folder, everything inside of it is also copied. If I “delete” a said folder, everything inside of it is also deleted (Figure 1.1).
