So far as Azure itself is concerned, a blob represents one or blocks of binary data. Much like data on your local hard drive, the notion of directories, files, and the tree-like hierarchical model so familiar to most users is imposed upon the stored data as an abstraction. In the case of your local hard drive, this model is implemented by the operating system. Within the Windows Azure storage model, there is no OS to impose such structure. Organization and interpretation of the data structure is left up to the client. It is in this way that we are able to store any type of data on the Blob storage platform, and similarly why blob storage is easily consumed by multiple languages and useable from any platform – the structure of the data is platform agnostic.
