Depends on your operating system. For any system not Chrome OS, folder creation is an organizational must. Your hard drive stores data sequentially in the form of bits. Whenever you want to access information on your hard drive, the drive has to, much like an array in programming, run through all the data until it comes across the desired file. This, as you could probably imagine, is cumbersome. We, as the users, have the luxury of not having to deal with that kind of information acquisition. We can create folders and directories into which we can place files. The reason I mentioned Chrome OS earlier, was because Chrome OS stores just about everything in the cloud. There isn't any real need to create directories on a Chrome system because all of that data can be managed and stored on Google's servers, as opposed to in files and organized by yourself.

The three tiers in a three-tier architecture are:
Presentation Tier: Occupies the top level and displays information related to services available on a website. This tier communicates with other tiers by sending results to the browser and other tiers in the network.
Middle Tier: Also called the application tier, logic tier, business logic or logic tier, this tier is pulled from the presentation tier. It controls application functionality by performing detailed processing.
Data Tier: Houses database servers where information is stored and retrieved. Data in this tier is kept independent of application servers or business logic.
