A folder is just like those you are familiar with on your own computer, a place to store documents and other folders.

If you want, you can also give information about the folder (what it is for, for example) which appears under the folder name.

Folders are catgeorized to reflect the structure of your project. For example a publication may have regular editions, each of which has sections which contain articles. The folder hierarchy can reflect this.

You might think of an article as a Word document, for example. However, if it has pictures as well, it may be helpful to create an article folder to hold all the content, pictures too, rather than having article documents gathered together in a single folder.

On the other hand, you don't need a folder to store multiple versions of a document - that's what documents do naturally.
