Recall the diagram on the last page...

Just as the two drives are in "My Computer", the C: drive has folders in it as well. The folders "~mssetup.t", "Acrobat3", "All Documents", etc. are all contained within C:. This is where we draw the analogy of a filing cabinet. You have the Cabinet as a whole (My Computer), then you have Drawers (C: and A. Inside the drawers are folders (Acrobat3, All Documents), and inside the folders may be sub-folders or the papers themselves (files).

Notice the plus (+) signs by certain folders in the diagram above. Those indicate the folder has other sub-folders contained within. Click on the plus sign, and the tree will expand further. See the next page for more detail.
