Folder Structures:

The directory structure is the organization of files into a hierarchy of folders. It should be stable; it should not fundamentally change, only be added to. Computers have used the folder metaphor for decades as a way to help users keep track of where something can be found.

Naming Conventions:

A naming convention is a convention for naming things. Conventions differ in their intents, which may include to allow useful information to be deduced from the names based on regularities.
