When Windows Explorer displays your computer as a filing cabinet, it means that it stores and displays your files in folders and subfolders. Windows Explorer is structured in a similar manner to a tree. The root folder is like the main root of the tree and the tree trunk. The branches and leaves are like the subfolders that can go down to as many levels as you require them to. It is important to arrange your files by category, eg. photos or music, and then by subcategory. In the photos category, you can arrange your photos by place and date etc.
